In Brief: On this site you will find pictures and information about some of the electronic, electrical and electrotechnical technology relics that the Frank Sharp Private museum has accumulated over the years .

Premise: There are lots of vintage electrical and electronic items that have not survived well or even completely disappeared and forgotten.

Or are not being collected nowadays in proportion to their significance or prevalence in their heyday, this is bad and the main part of the death land. The heavy, ugly sarcophagus; models with few endearing qualities, devices that have some over-riding disadvantage to ownership such as heavy weight,toxicity or inflated value when dismantled, tend to be under-represented by all but the most comprehensive collections and museums. They get relegated to the bottom of the wants list, derided as 'more trouble than they are worth', or just forgotten entirely. As a result, I started to notice gaps in the current representation of the history of electronic and electrical technology to the interested member of the public.


Following this idea around a bit, convinced me that a collection of the peculiar alone could not hope to survive on its own merits, but a museum that gave equal display space to the popular and the unpopular, would bring things to the attention of the average person that he has previously passed by or been shielded from. It's a matter of culture. From this, the Obsolete Technology Tellye Web Museum concept developed and all my other things too. It's an open platform for all electrical Electronic TV technology to have its few, but NOT last, moments of fame in a working, hand-on environment. We'll never own Colossus or Faraday's first transformer, but I can show things that you can't see at the Science Museum, and let you play with things that the Smithsonian can't allow people to touch, because my remit is different.

There was a society once that was the polar opposite of our disposable, junk society. A whole nation was built on the idea of placing quality before quantity in all things. The goal was not “more and newer,” but “better and higher" .This attitude was reflected not only in the manufacturing of material goods, but also in the realms of art and architecture, as well as in the social fabric of everyday life. The goal was for each new cohort of children to stand on a higher level than the preceding cohort: they were to be healthier, stronger, more intelligent, and more vibrant in every way.

The society that prioritized human, social and material quality is a Winner. Truly, it is the high point of all Western civilization. Consequently, its defeat meant the defeat of civilization itself.

Today, the West is headed for the abyss. For the ultimate fate of our disposable society is for that society itself to be disposed of. And this will happen sooner, rather than later.

OLD, but ORIGINAL, Well made, Funny, Not remotely controlled............. and not Made in CHINA.

TELEVIDEON MOD. TEE112 YEAR 1978.



The TELEVIDEON MOD. TEE112  is a 12 inches (31cm) portable little B/W television with 8 programs keyboard preselection with potentiometric tuning system.
The mechanical turret approach to television tuning has been used almost exclusively for the past 60 years. Even though replete with the inherent disadvantages of mechanical complexity, unreliability and cost, such apparatus has been technically capable of performing its intended function and as a result the consumer has had to bear the burdens associated with the device. However, with the " recent "  Broadcast demands for parity of tuning for UHF and VHF channels, the increasing number of UHF and cable TV stations have imposed new tuning performance requirements which severely tax the capability of the mechanical turret tuner. Consequently, attempts are now being made to provide all electronic tuning to meet the new requirements.

 One " " new " " tuning system currently being incorporated in some television receivers uses a varactor tuner which overcomes some of the disadvantages of mechanical turret tuner by accomplishing tuning electronically. As the name indicates, the heart of such a tuner is a varactor diode which is used as a capacitive tuning element in the RF and local oscillator sections. In this system, channel selection is made by applying a given reverse bias voltage to the varactor to change its electrical capacitance. The channel selection biasing can be performed by mechanically or electrically switching approximately 5 or many more preset potentiometers.
The invention relates to a tuning unit with bandswitch for high frequency receivers, especially radio and television receivers, having a potentiometer system for the control of capacity diodes, the said potentiometer system consisting of a plurality of parallel resistance paths along which wiper contacts can be driven by means of screw spindles disposed adjacent one another in a common insulating material housing in which a bandswitch formed of metal rods is associated with each tuning spindle.
In these tuning units, the working voltages of the capacity diodes in the tuning circuits are recorded once a precise tuning to the desired frequency has been performed. A potentiometer tuning system has great advantages over the formerly used channel selectors operating with mechanically adjustable capacitors (tuning condensers) or mechanically adjustable inductances (variometers), mainly because it is not required to have such great precision in its tuning mechanism.
Tuning units with bandswitches formed of variable resistances and combined with interlocking pushbuttons controlling the supply of recorded working voltages to capacity diodes are known. Channel selection is accomplished by depressing the knobs, and the tuning or fine tuning are performed by turning the knobs. The resistances serving as voltage dividers in these tuning units are combined into a component unit such that they are in the form of a ladderlike pattern on a common insulating plate forming the cover of the housing in which the tuning spindles and wiper contacts corresponding to the variable resistances are housed. The number of resistances corresponds to the number of channels or frequencies which are to be recorded. The wiper contact picks up a voltage which, when applied to the capacity diodes determines their capacitance and hence the frequency of the corresponding oscillating circuit. The adjustment of the wipers is performed by turning the tuning spindle coupled to the tuning knob. By the depression of a button the electrical connection between a contact rod and a tuning spindle is brought about and thus the selected voltage is applied to the capacity diodes. Since the push buttons release one another, it is possible simply by depressing another button to tune to a different receiving frequency or a different channel, as the case may be.
The problem with such arrangement is that it quite seriously limits the number of channels available to the consumer. Additionally, it suffers from the drawback that all potentiometers require adjusting for the desired channels. The VHF channels are usually factory adjusted while the six UHF channels require on-location adjustment. Moreover, using this arrangement, the only indication--during adjustment--of which channel is selected is by station identification.
All commands are above the cabinet located and was possible to applicate a plastic front screen over the crt face.
It has a Transistorized horizontal deflection circuits  made up of a horizontal switching or output transistor, a diode, one or more capacitors and a deflection winding. The output transistor, operating as a switch, is driven by a horizontal rate square wave signal and conducts during a portion of the horizontal trace interval. A diode, connected in parallel with the transistor, conducts during the remainder of the trace interval. A retrace capacitor and the deflection yoke winding are coupled in parallel across the transistor-diode combination. Energy is transferred into and out of the deflection winding via the diode and output transistor during the trace interval and via the retrace capacitor during the retrace interval.
In some television receivers, the collector of the horizontal output transistor is coupled to the B+ power supply through the primary windings of the high voltage transformer.


Televideon - Radio and Television; Italy   was a manufacturer of record player and tvs. The brand was from the FORMENTI group.

Television set kindly donated to me by Marshal Elia Z.


FORMENTI GROUP HISTORY It was founded in Desio ( Milan ) from Carlo Formenti in 1947 , under the name Carlo Formenti sas, and began his activities with the construction of radio , designed by the same founder, private label and under contract with other brands.

In 1953 the activities were moved to a new factory with 80 employees and was launched early production of TV sets in black and white , mostly as a subcontractor for major brands like Telefunken , Singer and Siemens .

Three years later began exports to foreign countries, and always as a subcontractor produced devices with trademarks for the large retail chains in Europe.


In 1961 took over the Italian plant of U.S. Admiral of Concorezzo with its 1,000 employees and a production capacity of 500 units per day, the license for the brand , and continued with the production of television and radio.
Admiral was formed Formenti SpA based in Milan , Lombardy and the company began its period of expansion so that within a few years led her to be one of the largest in the industry nationally.

Moreover, the production was extended to the field of "white" with the start of production of washing machines .

During the sixties , the head office and administration of the company, which changed its name to Industrie Formenti SpA Italy, was moved to Liss .

In 1972 was inaugurated a new plant in Sessa Aurunca for the production of color televisions with brands Admiral, Phoenix , Philco , and Televideon Uranya. Formenti was actually the first in Italy to produce the equipment, but until 1976 were marketed exclusively in the Central European countries, especially France and Germany , where for some time had already begun broadcasting in color.

Since 1983 the Group Formenti appeared on the market with another brand, White-Westinghouse , which became the most important with TVs, VCRs and household products from the same company Brianza.
In subsequent years Formenti used other brands as DuMont and Schaub-Lorenz .

Partially affected by the general crisis of the Italian electronic, in 1984 the public financial REL entered the capital Formenti record the 27.75% of the shares . The company, which by then had 580 employees scattered in the two plants, however, was one of the few entries in orbit REL able to repair their accounts in a short time.

In 1989 was started the modernization and extension of the establishment of Sessa, the installation of assembly automation , which allowed the company to undergo an increase in productivity from 300 to 2,200 pieces per day,The establishment of Concorezzo was instead intended to produce a new monitor and display for professional computer and ATM .

The company's continued A successful period during the nineties . Its sales went from over 108 billion lire in 1991 to 310 made in 1999 . Meanwhile, the Group acquired it in Monza 1997 the brand Imperial and the failed Sèleco , noting the brands Brionvega and Tandberg and the establishment of Pordenone (activated in 1998 ), and finally the Formenti family formed a new group called Sèleco-Formenti SpA, the which Charles, the founder, assumed the presidency, while the sons John and Julius, held the positions of CEO and director, respectively .


But since the year 2000 for Formenti begins a period of severe crisis. The company's balance sheet records a large deficit due to declining sales, the latter factor caused by the aggressive competition of producers Turkish color TV, put on the market at competitive prices clearly and without adequate anti- dumping on the part of ' European Union .

Also as a result of the difficulties facing the company, it decided to close the two plants Concorezzo ( 2000 ) and Sessa Aurunca ( 2003 ), respectively, 130 and 440 employees, as well as staff reductions in the Friuli .

In 2004 the company was put into liquidation , and then it is decided by the commissioner, the Court of Monza that appointment as curator Professor. Francesco Fimmanò. After a long period of unemployment benefits for workers of the company, shed of Pordenone and brands Sèleco, Brionvega and Imperial in 2006 are awarded to the Super / / Fluo , a company based in Udine owned by the brothers Carlo and Marco Asquini. The new property will only tempoi to produce some brand Imperial model tv, radio, and a Seleco brand new LCD TV brand Brionvega before the bankruptcy of the same. From this to save the brand Super / / Fluo, while the other brands owned and acquired by Formenti will pass to the new property called Selek Brionvega Technology and the mark for both audio and video production will switch to SIM2 Multimedia, the renowned Italian company field projectors.


Today  this industry and brand are DEAD !!!


TELEVIDEON MOD. TEE112 CHASSIS VT877 (701461305) INTERNAL VIEW.










The tuning circuits has a large knob potentiometers tuning system which use voltage controlled capacitances such as varactor diodes as the frequency determining elements.

How AFC Circuit Works in B/W Analog Television Receiver:

Push-Button tuning on u.h.f. while being very convenient often leaves a margin of mistuning, especially after some wear and tear has occurred on the mechanism. Even dial tuning can lead to errors due to the difficulty many people experience in judging the correct point. Oscillator drift due to temperature changes can also cause mistuning. Automatic frequency control (a.f.c.) will correct all these faults. The vision carrier when the set is correctly tuned on u.h.f. is at 39.5MHz as it passes down the i.f. strip. Thus if at the end of the i.f. strip a discriminator tuned circuit is incorporated centred on 39.5MHz the discriminator output will be zero at 39.5MHz and will move positively' one side of 39.5MHz and negatively the other as the tuning drifts. This response is shown in Fig. 1.

If the tuning is not correct then the discriminator output is not zero and if this output is applied to change the reverse bias on a tuning diode mounted in the oscillator section of the u.h.f. tuner it will correct most of the error. Tuning, varicap or varactor diodes-to give them a few of their names-are junction diodes normally operated with reverse bias but not sufficient to bias them into the breakdown region in which zener diodes operate. The greater the reverse bias the lower their capacitance: a typical curve, for the PHILIPS BB105 or STC BA141 tuning diode, is shown in Fig. 2. All diodes exhibit this basic type of characteristic but special diodes have to be used for u.h.f. because they must not introduce any excessive loss into the tuned circuits they control. In other words, just as a coil has to have a good Q so does a varicap diode. Normally, we don't worry about the Q of a capacitor as it is usually very good. However, a tuning diode is not a true capacitor. It has, for example, leakage current so the Q of the diode is a factor which has to be considered. The diode manufacturer however will have considered these points and if you buy a diode specified for u.h.f. use you will have no trouble. These points have been mentioned to clear up any misunderstandings and to show why any old diode won't do.

Basic AFC System
To return to our TV set, if the oscillator frequency is too high then the vision carrier frequency will also be too high and in the simple arrangement shown in Fig. 3 the discriminator will give a negative signal to decrease the bias on the tuning diode thus increasing its capacitance and in turn reducing the oscillator frequency and correcting the error. Note that in this diagram the reverse bias on the diode is applied to its cathode. It is therefore positive with respect to ground so that a negative signal from the discriminator will reduce the positive voltage on the diode thus reducing its bias and increasing its capacitance. In this arrangement the diode is biased somewhere near the mid point of its characteristic by the positive d.c. bias fed into one side of the discriminator. The discriminator thus adds to or subtracts from this d.c. bias.

AFC Loop Gain:
The amount by which the error is reduced depends on the gain of the circuit. An estimate of the gain required must first be made by guessing how much error is likely to be given by your push -buttons or hand tuning: 1MHz would be an outside figure as a tuning error of that magnitude would produce a very bad picture of low definition in one direction and badly broken up in the other. This error should be reduced to about 100kHz to be really unnoticeable, indicating a required gain of ten. In fitting a.f.c. to an existing set some measure- ments should be done as an experiment before finally deciding on the circuit gain. The first thing to do is  to add the suggested discriminator to the i.f. strip. As the circuit (Fig. 4) shows a Foster -Seeley type discriminator is used and with the coils specified and the driver circuit shown it should give ±4V for 0.5MHz input variation.

EXAMPLE of Circuit Description:
The driver stage Tr1 takes a small sample signal from the i.f. strip but this should be large enough to drive Tr1 into saturation. That is to say Tr1 is a limiter stage so that the signal amplitude applied to the discriminator coil L2 stays constant over the normal range of signal levels. Trl is biased at approximately 7mA which, according to the original report ("Simple a.f.c. system for 625 -line TV receivers" by P. Bissmire, PHILIPS Technical Communications, March, 1970), gives the best limiting performance. C1, R14 and R3 damp the stage to prevent oscillation. C2 decouples the power feed and should be close to the circuit. The coil former and can are the normal ones used for TV sets and so should be easily obtainable: the former diameter is 5mm. and length 40mm. and winding details are given in Fig. 5.

The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the developed apparates both tubes or transistors.


Therefore a stable AFC circuit is developed:

A superheterodyne receiver having an automatic intermediate frequency control circuit with means to prevent the faulty regulation thereof. The receiver has means for receiving a radio frequency signal and mixing the same with the output of a superheterodyne oscillator. This produces an intermediate frequency signal which is coupled to a frequency or phase discriminator to produce an error signal for controlling the frequency of the superheterodyne oscillator. A regulation circuit is provided having an electronic switch to interrupt the feedback circuit when only unwanted frequencies tend to produce faulty regulation of the superheterodyne oscillator.


Power supply is realized with mains transformer and Linear transistorized power supply stabilizer, A DC power supply apparatus includes a rectifier circuit which rectifies an input commercial AC voltage. The rectifier output voltage is smoothed in a smoothing capacitor. Voltage stabilization is provided in the stabilizing circuits by the use of Zener diode circuits to provide biasing to control the collector-emitter paths of respective transistors.A linear regulator circuit according to an embodiment of the present invention has an input node receiving an unregulated voltage and an output node providing a regulated voltage. The linear regulator circuit includes a voltage regulator, a bias circuit, and a current control device.

In one embodiment, the current control device is implemented as an NPN bipolar junction transistor (BJT) having a collector electrode forming the input node of the linear regulator circuit, an emitter electrode coupled to the input of the voltage regulator, and a base electrode coupled to the second terminal of the bias circuit. A first capacitor may be coupled between the input and reference terminals of the voltage regulator and a second capacitor may be coupled between the output and reference terminals of the voltage regulator. The voltage regulator may be implemented as known to those skilled in the art, such as an LDO or non-LDO 3-terminal regulator or the like.
The bias circuit may include a bias device and a current source. The bias device has a first terminal coupled to the output terminal of the voltage regulator and a second terminal coupled to the control electrode of the current control device. The current source has an input coupled to the first current electrode of the current control device and an output coupled to the second terminal of the bias device. A capacitor may be coupled between the first and second terminals of the bias device.
In the bias device and current source embodiment, the bias device may be implemented as a Zener diode, one or more diodes coupled in series, at least one light emitting diode, or any other bias device which develops sufficient voltage while receiving current from the current source. The current source may be implemented with a PNP BJT having its collector electrode coupled to the second terminal of the bias device, at least one first resistor having a first end coupled to the emitter electrode of the PNP BJT and a second end, a Zener diode and a second resistor. The Zener diode has an anode coupled to the base electrode of the PNP BJT and a cathode coupled to the second end of the first resistor. The second resistor has a first end coupled to the anode of the Zener diode and a second end coupled to the reference terminal of the voltage regulator. A second Zener diode may be included having an anode coupled to the cathode of the first Zener diode and a cathode coupled to the first current electrode of the current control device.
A circuit is disclosed for improving operation of a linear regulator, having an input terminal, an output terminal, and a reference terminal. The circuit includes an input node, a transistor, a bias circuit, and first and second capacitors. The transistor has a first current electrode coupled to the input node, a second current electrode for coupling to the input terminal of the linear regulator, and a control electrode. The bias circuit has a first terminal for coupling to the output terminal of the linear regulator and a second terminal coupled to the control electrode of the transistor. The first capacitor is for coupling between the input and reference terminals of the linear regulator, and the second capacitor is for coupling between the output and reference terminals of the linear regulator. The bias circuit develops a voltage sufficient to drive the control terminal of the transistor and to operate the linear regulator. The bias circuit may be a battery, a bias device and a current source, a floating power supply, a charge pump, or any combination thereof. The transistor may be implemented as a BJT or FET or any other suitable current controlled device.


Power Supply: The examples chosen are taken from manufacturers' circuit diagrams and are usually simplified to emphasise the fundamental nature of the circuit. For each example the particular transistor properties that are exploited to achieve the desired performance are made clear. As a rough and ready classification the circuits are arranged in order of frequency: this part is devoted to circuits used at zero frequency, field frequency and audio frequencies. Series Regulator Circuit Portable television receivers are designed to operate from batteries (usually 12V car batteries) and from the a.c. mains. The receiver usually has an 11V supply line, and circuitry is required to ensure that the supply line is at this voltage whether the power source is a battery or the mains. The supply line also needs to have good regulation, i.e. a low output resistance, to ensure that the voltage remains constant in spite of variations in the mean current taken by some of the stages in the receiver. Fig. 1 shows a typical circuit of the power -supply arrangements. The mains transformer and bridge rectifier are designed to deliver about 16V. The battery can be assumed to give just over 12V. Both feed the regulator circuit Trl, Tr2, Tr3, which gives an 11V output and can be regarded as a three -stage direct -coupled amplifier. The first stage Tr 1 is required to give an output current proportional to the difference between two voltages, one being a constant voltage derived from the voltage reference diode D I (which is biased via R3 from the stabilised supply). The second voltage is obtained from a preset potential divider connected across the output of the unit, and is therefore a sample of the output voltage. In effect therefore Tr 1 compares the output voltage of the unit with a fixed voltage and gives an output current proportional to the difference between them. Clearly a field-effect transistor could do this, but the low input resistance of a bipolar transistor is no disadvantage and it can give a current output many times that of a field-effect transistor and is generally preferred therefore. The output current of the first stage is amplified by the two subsequent stages and then becomes the output current of the unit. Clearly therefore Tr2 and Tr3 should be current amplifiers and they normally take the form of emitter followers or common emitter stages (which have the same current gain). By adjusting the preset control we can alter the fraction of the output voltage' applied to the first stage and can thus set the output voltage of the unit at any desired value within a certain range. By making assumptions about the current gain of the transistors we can calculate the degree of regulation obtainable. For example, suppose the gain of Tr2 and Tr3 in cascade is 1,000, and that the current output demanded from the unit changes by 0.1A (for example due to the disconnection of part of the load). The corresponding change in Tr l's collector current is 0.1mA and, if the standing collector current of Tr 1 is 1mA, then its mutual conductance is approximately 4OmA/V and the base voltage must change by 2.5mV to bring about the required change in collector current. If the preset potential divider feeds one half of the output voltage to Tr l's base, then the change in output voltage must be 5mV. Thus an 0.1A change in output current brings about only 5mV change in output voltage: this represents an output resistance of only 0.0552.


TDA1170 vertical deflection FRAME DEFLECTION INTEGRATED CIRCUITGENERAL DESCRIPTION f The TDA1170 and TDA1270 are monolithic integrated
circuits designed for use in TV vertical deflection systems. They are manufactured using
the Fairchild Planar* process.
Both devices are supplied in the 12-pin plastic power package with the heat sink fins bent
for inse
rtion into the printed circuit board.
The TDA1170 is designed primarily for large and small screen black and white TV
receivers and industrial TV monitors. The TDA1270 is designed primarily for driving
complementary vertical deflection output stages in color TV receivers and industrial
monitors.
APPLICATION INFORMATION (TDA1170)
The vertical oscillator is directly synchronized by the sync pulses (positive or negative); therefore its free
running frequency must be lower than the sync frequency. The use of current feedback causes the yoke
current to be independent of yoke resistance variations due to thermal effects, Therefore no thermistor is
required in series with the yoke. The flyback generator applies a voltage, about twice the supply voltage, to
the yoke. This produces a short flyback time together with a high useful power to dissipated power
ratio.




GENERAL BASIC TRANSISTOR LINE OUTPUT STAGE OPERATION:

The basic essentials of a transistor line output stage are shown in Fig. 1(a). They comprise: a line output transformer which provides the d.c. feed to the line output transistor and serves mainly to generate the high -voltage pulse from which the e.h.t. is derived, and also in practice other supplies for various sections of the receiver; the line output transistor and its parallel efficiency diode which form a bidirectional switch; a tuning capacitor which resonates with the line output transformer primary winding and the scan coils to determine the flyback time; and the scan coils, with a series capacitor which provides a d.c. block and also serves to provide slight integration of the deflection current to compensate for the scan distortion that would otherwise be present due to the use of flat screen, wide deflection angle c.r.t.s. This basic circuit is widely used in small -screen portable receivers with little elaboration - some use a pnp output transistor however, with its collector connected to chassis.

Circuit Variations:
Variations to the basic circuit commonly found include: transposition of the scan coils and the correction capacitor; connection of the line output transformer primary winding and its e.h.t. overwinding in series; connection of the deflection components to a tap on the transformer to obtain correct matching of the components and conditions in the stage; use of a boost diode which operates in identical manner to the arrangement used in valve line output stages, thereby increasing the effective supply to the stage; omission of the efficiency diode where the stage is operated from an h.t. line, the collector -base junction of the line output transistor then providing the efficiency diode action without, in doing so, producing scan distortion; addition of inductors to provide linearity and width adjustment; use of a pair of series -connected line output transistors in some large -screen colour chassis; and in colour sets the addition of line convergence circuitry which is normally connected in series between the line scan coils and chassis. These variations on the basic circuit do not alter the basic mode of operation however.

Resonance
The most important fact to appreciate about the circuit is that when the transistor and diode are cut off during the flyback period - when the beam is being rapidly returned from the right-hand side of the screen to the left-hand side the tuning capacitor together with the scan coils and the primary winding of the line output transformer form a parallel resonant circuit: the equivalent circuit is shown in Fig. 1(b). The line output transformer primary winding and the tuning capacitor as drawn in Fig. 1(a) may look like a series tuned circuit, but from the signal point of view the end of the transformer primary winding connected to the power supply is earthy, giving the equivalent arrangement shown in Fig. 1(b).

The Flyback Period:
Since the operation of the circuit depends mainly upon what happens during the line flyback period, the simplest point at which to break into the scanning cycle is at the end of the forward scan, i.e. with the beam deflected to the right-hand side of the screen, see Fig. 2. At this point the line output transistor is suddenly switched off by the squarewave drive applied to its base. Prior to this action a linearly increasing current has been flowing in the line output transformer primary winding and the scan coils, and as a result magnetic fields have been built up around these components. When the transistor is switched off these fields collapse, maintaining a flow of current which rapidly decays to zero and returns the beam to the centre of the screen. This flow of current charges the tuning capacitor, and the voltage at A rises to a high positive value - of the order of 1- 2k V in large -screen sets, 200V in the case of mains/battery portable sets. The energy in the circuit is now stored in the tuning capacitor which next discharges, reversing the flow of current in the circuit with the result that the beam is rapidly deflected to the left-hand side of the screen - see Fig. 3. When the tuning capacitor has discharged, the voltage at A has fallen to zero and the circuit energy is once more stored in the form of magnetic fields around the inductive components. One half -cycle of oscillation has occurred, and the flyback is complete.

Energy Recovery:
First Part of Forward Scan The circuit then tries to continue the cycle of oscillation, i.e. the magnetic fields again collapse, maintaining a current flow which this time would charge the tuning capacitor negatively (upper plate). When the voltage at A reaches about -0.6V however the efficiency diode becomes forward biased and switches on. This damps the circuit, preventing further oscillation, but the magnetic fields continue to collapse and in doing so produce a linearly decaying current flow which provides the first part of the forward scan, the beam returning towards the centre of the screen - see Fig. 4. The diode shorts out the tuning capacitor but the scan correction capacitor charges during this period, its right-hand plate becoming positive with respect to its left-hand plate, i.e. point A. Completion of Forward Scan When the current falls to zero, the diode will switch off. Shortly before this state of affairs is reached however the transistor is switched on. In practice this is usually about a third of the way through the scan. The squarewave applied to its base drives it rapidly to saturation, clamping the voltage at point A at a small positive value - the collector emitter saturation voltage of the transistor. Current now flows via the transistor and the primary winding of the line output transformer, the scan correction capacitor discharges, and the resultant flow of current in the line scan coils drives the beam to the right-hand side of the screen see Fig. 5.

Efficiency:
The transistor is then cut off again, to give the flyback, and the cycle of events recurs. The efficiency of the circuit is high since there is negligible resistance present. Energy is fed into the circuit in the form of the magnetic fields that build up when the output transistor is switched on. This action connects the line output transformer primary winding across the supply, and as a result a linearly increasing current flows through it. Since the width is
dependent on the supply voltage, this must be stabilised.

Harmonic Tuning:
There is another oscillatory action in the circuit during the flyback period. The considerable leakage inductance between the primary and the e.h.t. windings of the line output transformer, and the appreciable self -capacitance present, form a tuned circuit which is shocked into oscillation by the flyback pulse. Unless this oscillation is controlled, it will continue into and modulate the scan. The technique used to overcome this effect is to tune the leakage inductance and the associated capacitance to an odd harmonic of the line flyback oscillation frequency. By doing this the oscillatory actions present at the beginning of the scan cancel. Either third or fifth harmonic tuning is used. Third harmonic tuning also has the effect of increasing the amplitude of the e.h.t. pulse, and is generally used where a half -wave e.h.t. rectifier is employed. Fifth harmonic tuning results in a flat-topped e.h.t. pulse, giving improved e.h.t. regulation, and is generally used where an e.h.t. tripler is employed to produce the e.h.t. The tuning is mainly built into the line output transformer, though an external variable inductance is commonly found in colour chassis so that the tuning can be adjusted. With a following post I will go into the subject of modern TV line timebases in greater detail with other models and technology shown here at  Obsolete Technology Tellye !

USING EITHER TRANSISTORS OR THYRISTORS.

In a conventional line scan circuit, such as in the Plessey or Mullard TBA920 integrated circuit, a phase-locked oscillator is synchronized with the incoming horizontal synchronization (H-sync) pulses to provide a control signal to the line output circuit. This ensures that oscillation is maintained in the absence of the H-sync signal, for example, during maintenance in the case of a display terminal, or, in the case of a TV receiver, when untuned, and noise on the incoming signal is smoothed out. The phase relationship between the output and input is very precisely maintained to prevent line tearing and other picture defects.

Flyback voltage pulses occur at the terminals of the yoke of the cathode ray tube (CRT) between successive horizontal scans of the electron beam while the screen is blanked. Due to component tolerances and temperature effects, the flyback voltage pulses may be broadened and unless the broadened pulse falls within the blanking period, picture defects can occur. Conventionally, this problem has been overcome by designing the CRT circuits to allow a broad blanking period between the line scans: however, this has a deleterious effect on the efficiency of the display.
The design of the driver and horizontal output transistor stages is very critical. In typical circuits the horizontal output transistor conducts during the last half of the trace interval and is sharply cut-off to initiate retrace. During retrace a large retrace or flyback voltage appears at the collector of the horizontal output transistor. If the transistor is conducting when this voltage appears, the retrace current will be altered and the transistor will dissipate excessive power which generally will result in damage to the transistor. Since the horizontal output transistor is conducting heavily immediately before retrace is initiated, the stored charge in the base and collector regions of the transistor must be removed before the transistor will cease conducting collector current. Normally this stored charge is removed by applying a negative pulse to the base of an NPN transistor to cause a reverse base current to flow. This negative pulse, however, should be applied only as long as necessary to alleviate the voltage stress on the collector-base junction during retrace. R. J. Walker and R. Yu, "Horizontal Output Transistor Base Circuit Design," IEEE Transactions on Broadcast and Television Receivers, Vol. BTR-20, Aug. 1974, pp. 185-192, describe the various design requirements for the base circuit of the horizontal output transistor.
The above design requirements place severe limitations on the horizontal driver transistor and transformer design. In typical circuits conduction by the driver transistor during retrace and the first half of trace switches the output transistor off. The driver transformer stores energy during conduction by the driver transistor which is used to provide forward base current to the horizontal output transistor during the following conduction interval of the output transistor. Accordingly, the drive current in the primary winding must be of the proper amplitude and duration to maintain the horizontal output transistor in conduction in saturation during the second half of trace. When the driver transistor turns on again, the initial current flow through the primary winding of the driver transformer provides a turn-off pulse to the base of the output transistor. The amplitude and duration of the turn-off pulse are dependent on the inductances and the turns ratio of the driver transformer windings.

 THE TBA920 SYNC/TIMEBASE IC It has been quite common for some time for sync separation to be carried out in an i.c. but until 1971 this was as far as i.c.s had gone in television receiver timebase circuitry. With the recent introduction of the delta featured 110°  colour series however i.c.s have gone a step farther since this chassis uses a TBA920 as sync separator and line generator. A block diagram of this PHILIPS /Mullard  i.c. is shown in Fig. 1.
The video signal at about 2-7V peak -peak is fed to the sync separator section at pin 8, the composite sync waveform appearing at pin 7.
The noise gate switches off the sync separator when a positive -going input pulse is fed in at pin 9, an external noise limiter circuit being required .
The line sync pulses are shaped by R1 /C1 /C2/R2 and fed in to the oscillator phase detector section at pin 6.
The line oscillator waveform is fed internally to the oscillator phase detector circuit which produces at pin 12 a d.c. potential which is used to lock the line oscillator to the sync pulse frequency, the control potential being fed in at pin 15. The oscillator itself is a CR type whose waveform is produced by the charge and discharge of the external capacitor (C7) connected to pin 14. The oscillator frequency is set basically by C7 and R6 and can be varied by the control potential appearing at pin 15 from pin 12 and the external line hold control. Internally the line oscillator feeds a triangular waveform to the oscillator and flyback phase detector sections and the pulse width control section. The coincidence detector section is used to set the time constant of the oscillator phase detector circuit. It is fed internally with sync pulses from the sync separator section, and with line flyback pulses via pin 5. When the flyback pulses are out of phase with the sync pulses the impedance looking into pin 11 is high (21(Q). When the pulses are coincident the impedance falls to about 150Q and the oscillator phase detector circuit is then slow acting. The effect of this is to give fast pull -in when the pulses are out of sync and good noise immunity when they are in sync. The coincidence detector is controlled by the voltage on pin 10. When the sync and flyback pulses are in sync C3 is charged: when they are out of sync C3 discharges via R3. VTR use has been taken into consideration here. With a video recorder it is necessary to be able to follow the sync pulse phase variations that occur as a result of wow and flutter in the tape transport system, while noise is much less of a problem. For use with a VTR therefore the network on pin 10 can simply be left out so that the oscillator phase detector circuit is always fast acting. A second control loop is used to adjust the timing of the pulse output obtained from pin 2 to take into account the delay in the line output stage. The fly back phase detector compares the frequency of the flyback pulses fed in at pin 5 with the oscillator signal which has already been synchronised to the sync pulse frequency.
Any phase difference results in an output from pin 4 which is integrated and fed into the pulse width control section at pin 3. The potential at pin 3 sets the width of the output pulse obtained at pin 2: with a high positive voltage (via R11 and R12) at pin 3 a 1:1 mark -space ratio out- put pulse (32/us on, 32/us off) will be produced while a low potential at pin 3 (negative output at pin 4) will give a 16us output pulse at  the same frequency. The action of this control loop continues until the fly- back pulses are in phase with a fixed point on the oscillator waveform: the flyback pulses are then in phase with the sync pulses and delays in the line output stage are compensated. The output obtained at pin 2 is of low impedance and is suitable for driving valves, transistors or thyristors: R9 is necessary to provide current limiting.

PHONOLA (PHILIPS) 37KV1232 YEAR 1990.



The PHONOLA (PHILIPS) 37KV1232  is a 15 inches color television with 50 programs with vst tuning search and osd.On screen display (OSD) arrangements employed in video processing systems include a switching (or "multiplexing") network for switching between graphic image representative signals and normal video signals so that a graphic image can be displayed on the screen of a picture reproduction device either in place of the image represented by the video signals or together with (inserted in) the image. The graphic image can take the form of alphanumeric symbols or-pictorial graphics, and can be used to indicate status information, such as channel numbers or time, or operating instructions.

In an OSD arrangement for use in an analog video signal processing system, the multiplexing network typically operates to switch in levels corresponding to the desired intensity of respective portions of the graphic image at the time the graphic image portions are to be displayed. In such an arrangement the graphic image representative signals take the form of timing pulses which occur when the graphic image portions are to be displayed and are used to control the multiplexing network. Such an analog OSD arrangement can also be used in a digital video processing system, but requires that the video signals be first converted to analog form. While digital video signal processing systems typically include a digital-to-analog converter section in which the digital video signals are converted to analog form, it may be more cost effective for the OSD arrangement to be incorporated as an integral part of the digital video processing section.

The set is a simple color tv and was last Phonola / Philips model without AV Scart socket.


This models series was featuring the GR1AX a small monocarrier tv chassis briefly used before other types with SMPS isolated from mains since the GR1AX has direct mains SMPS supply.

Pictures are very bright and powerful.



Koninklijke Philips Electronics N.V. (Royal Philips Electronics Inc.), most commonly known as Philips, (Euronext: PHIA, NYSE: PHG) is a multinational Dutch electronics corporation.

Philips is one of the largest electronics companies in the world. In 2009, its sales were €23.18 billion. The company employs 115,924 people in more than 60 countries.

Philips is organized in a number of sectors: Philips Consumer Lifestyles (formerly Philips Consumer Electronics and Philips Domestic Appliances and Personal Care), Philips Lighting and Philips Healthcare (formerly Philips Medical Systems).
The company was founded in 1891 by Gerard Philips, a maternal cousin of Karl Marx, in Eindhoven, Netherlands. Its first products were light bulbs and other electro-technical equipment. Its first factory survives as a museum devoted to light sculpture. In the 1920s, the company started to manufacture other products, such as vacuum tubes (also known worldwide as 'valves'), In 1927 they acquired the British electronic valve manufacturers Mullard and in 1932 the German tube manufacturer Valvo, both of which became subsidiaries. In 1939 they introduced their electric razor, the Philishave (marketed in the USA using the Norelco brand name).
Philips was also instrumental in the revival of the Stirling engine.

As a chip maker, Philips Semiconductors was among the Worldwide Top 20 Semiconductor Sales Leaders.

In December 2005 Philips announced its intention to make the Semiconductor Division into a separate legal entity. This process of "disentanglement" was completed on 1 October 2006.

On 2 August 2006, Philips completed an agreement to sell a controlling 80.1% stake in Philips Semiconductors to a consortium of private equity investors consisting of Kohlberg Kravis Roberts & Co. (KKR), Silver Lake Partners and AlpInvest Partners. The sale completed a process, which began December 2005, with its decision to create a separate legal entity for Semiconductors and to pursue all strategic options. Six weeks before, ahead of its online dialogue, through a letter to 8,000 of Philips managers, it was announced that they were speeding up the transformation of Semiconductors into a stand-alone entity with majority ownership by a third party. It was stated then that "this is much more than just a transaction: it is probably the most significant milestone on a long journey of change for Philips and the beginning of a new chapter for everyone – especially those involved with Semiconductors".

In its more than 115 year history, this counts as a big step that is definitely changing the profile of the company. Philips was one of few companies that successfully made the transition from the electrical world of the 19th century into the electronic age, starting its semiconductor activity in 1953 and building it into a global top 10 player in its industry. As such, Semiconductors was at the heart of many innovations in Philips over the past 50 years.

Agreeing to start a process that would ultimately lead to the decision to sell the Semiconductor Division therefore was one of the toughest decisions that the Board of Management ever had to make.

On 21 August 2006, Bain Capital and Apax Partners announced that they had signed definitive commitments to join the expanded consortium headed by KKR that is to acquire the controlling stake in the Semiconductors Division.

On 1 September 2006, it was announced in Berlin that the name of the new semiconductor company founded by Philips is NXP Semiconductors.

Coinciding with the sale of the Semiconductor Division, Philips also announced that they would drop the word 'Electronics' from the company name, thus becoming simply Koninklijke Philips N.V. (Royal Philips N.V.).


PHILIPS FOUNDATION:

The foundations of Philips were laid in 1891 when Anton and Gerard Philips established Philips & Co. in Eindhoven, the Netherlands. The company begun manufacturing carbon-filament lamps and by the turn of the century, had become one of the largest producers in Europe. Stimulated by the industrial revolution in Europe, Philips’ first research laboratory started introducing its first innovations in the x-ray and radio technology. Over the years, the list of inventions has only been growing to include many breakthroughs that have continued to enrich people’s everyday lives.



In the early years of Philips &; Co., the representation of the company name took many forms: one was an emblem formed by the initial letters of Philips ; Co., and another was the word Philips printed on the glass of metal filament lamps.



One of the very first campaigns was launched in 1898 when Anton Philips used a range of postcards showing the Dutch national costumes as marketing tools. Each letter of the word Philips was printed in a row of light bulbs as at the top of every card. In the late 1920s, the Philips name began to take on the form that we recognize today.



The now familiar Philips waves and stars first appeared in 1926 on the packaging of miniwatt radio valves, as well as on the Philigraph, an early sound recording device. The waves symbolized radio waves, while the stars represented the ether of the evening sky through which the radio waves would travel.



In 1930 it was the first time that the four stars flanking the three waves were placed together in a circle. After that, the stars and waves started appearing on radios and gramophones, featuring this circle as part of their design. Gradually the use of the circle emblem was then extended to advertising materials and other products.



At this time Philips’ business activities were expanding rapidly and the company wanted to find a trademark that would uniquely represent Philips, but one that would also avoid legal problems with the owners of other well-known circular emblems. This wish resulted in the combination of the Philips circle and the wordmark within the shield emblem.



In 1938, the Philips shield made its first appearance. Although modified over the years, the basic design has remained constant ever since and, together with the wordmark, gives Philips the distinctive identity that is still embraced today.

The first steps of CRT production by Philips started in the thirties with the Deutsche Philips Electro-Spezial gesellschaft in Germany and the Philips NatLab (Physics laboratory) in Holland. After the introduction of television in Europe, just after WWII there was a growing demand of television sets and oscilloscope equipment. Philips in Holland was ambitious and started experimental television in 1948. Philips wanted to be the biggest on this market. From 1948 there was a small Philips production of television and oscilloscope tubes in the town of Eindhoven which soon developed in mass production. In 1976 a part of the Philips CRT production went to the town of Heerlen and produced its 500.000'th tube in 1986. In 1994 the company in Heerlen changed from Philips into CRT-Heerlen B.V. specialized in the production of small monochrome CRT's for the professional market and reached 1.000.000 produced tubes in 1996. In this stage the company was able to produce very complicated tubes like storage CRT's.
In 2001 the company merged into Professional Display Systems, PDS worked on LCD and Plasma technology but went bankrupt in 2009. The employees managed a start through as Cathode Ray Technology which now in 2012 has to close it's doors due to the lack of sales in a stressed market. Their main production was small CRT's for oscilloscope, radar and large medical use (X-ray displays). New experimental developments were small Electron Microscopy, 3D-TV displays, X-Ray purposes and Cathode Ray Lithography for wafer production. Unfortunately the time gap to develop these new products was too big.


28 of September 2012, Cathode Ray Technology (the Netherlands), the last Cathode Ray Tube factory in Europe closed. Ironically the company never experienced so much publicity as now, all of the media brought the news in Holland about the closure. In fact this means the end of mass production 115 years after Ferdinand Braun his invention. The rapid introduction and acceptation of LCD and Plasma displays was responsible for a drastic decrease in sales. Despite the replacement market for the next couple of years in the industrial, medical and avionics sector.
The numbers are small and the last few CRT producers worldwide are in heavy competition.

Gerard Philips:

Gerard Leonard Frederik Philips (October 9, 1858, in Zaltbommel – January 27, 1942, in The Hague, Netherlands) was a Dutch industrialist, co-founder (with his father Frederik Philips) of the Philips Company as a family business in 1891. Gerard and his younger brother Anton Philips changed the business to a corporation by founding in 1912 the NV Philips' Gloeilampenfabrieken. As the first CEO of the Philips corporation, Gerard laid with Anton the base for the later Philips multinational.



Early life and education

Gerard was the first son of Benjamin Frederik David Philips (1 December 1830 – 12 June 1900) and Maria Heyligers (1836 – 1921). His father was active in the tobacco business and a banker at Zaltbommel in the Netherlands; he was a first cousin of Karl Marx.



Career

Gerard Philips became interested in electronics and engineering. Frederik was the financier for Gerard's purchase of the old factory building in Eindhoven where he established the first factory in 1891. They operated the Philips Company as a family business for more than a decade.



Marriage and family

On March 19, 1896 Philips married Johanna van der Willigen (30 September 1862 – 1942). They had no children.

Gerard was an uncle of Frits Philips, whom he and his brother brought into the business. Later they brought in his brother's grandson, Franz Otten.


Gerard and his brother Anton supported education and social programs in Eindhoven, including the Philips Sport Vereniging (Philips Sports Association), which they founded. From it the professional football (soccer) department developed into the independent Philips Sport Vereniging N.V.



Anton Philips:

Anton Frederik Philips (March 14, 1874, Zaltbommel, Gelderland – October 7, 1951, Eindhoven) co-founded Royal Philips Electronics N.V. in 1912 with his older brother Gerard Philips in Eindhoven, the Netherlands. He served as CEO of the company from 1922 to 1939.



Early life and education

Anton was born to Maria Heyligers (1836 – 1921) and Benjamin Frederik David Philips (December 1, 1830 – June 12, 1900). His father was active in the tobacco business and a banker at Zaltbommel in the Netherlands. (He was a first cousin to Karl Marx.) Anton's brother Gerard was 16 years older.



Career

In May 1891 the father Frederik was the financier and, with his son Gerard Philips, co-founder of the Philips Company as a family business. In 1912 Anton joined the firm, which they named Royal Philips Electronics N.V.

During World War I, Anton Philips managed to increase sales by taking advantage of a boycott of German goods in several countries. He provided the markets with alternative products.

Anton (and his brother Gerard) are remembered as being civic-minded. In Eindhoven they supported education and social programs and facilities, such as the soccer department of the Philips Sports Association as the best-known example.

Anton Philips brought his son Frits Philips and grandson Franz Otten into the company in their times. Anton took the young Franz Otten with him and other family members to escape the Netherlands just before the Nazi Occupation during World War II; they went to the United States. They returned after the war.

His son Frits Philips chose to stay and manage the company during the occupation; he survived several months at the concentration camp of Vught after his workers went on strike. He saved the lives of 382 Jews by claiming them as indispensable to his factory, and thus helped them evade Nazi roundups and deportation to concentration camps.

Philips died in Eindhoven in 1951.



Marriage and family

Philips married Anne Henriëtte Elisabeth Maria de Jongh (Amersfoort, May 30, 1878 – Eindhoven, March 7, 1970). They had the following children:

* Anna Elisabeth Cornelia Philips (June 19, 1899 – ?), married in 1925 to Pieter Franciscus Sylvester Otten (1895 – 1969), and had:
