Richtige Fernseher haben Röhren!

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.

Many contemporary "televisions" (more correctly named as displays) would not have this level of staying power, many would ware out or require major services within just five years or less and of course, there is that perennial bug bear of planned obsolescence where components are deliberately designed to fail and, or manufactured with limited edition specificities..... and without considering........picture......sound........quality........

..............The bitterness of poor quality is remembered long after the sweetness of todays funny gadgets low price has faded from memory........ . . . . . .....
Don't forget the past, the end of the world is upon us! Pretty soon it will all turn to dust!

Have big FUN ! !

METZ 7096 CLASSIC COLOR (CH679G) YEAR 1980.







The METZ  7096 CLASSIC COLOR  (CH679G)  is a compact 26 inches (66cm) color television.

It has 30 programs VST tuning system, automatic search system, external loudspeaker connector, audio recorder din jack and headphones din jack.

The set was first METZ color television featuring the PHILIPS 30AX CRT TUBE and first time an Isolated from mains chassis design.
 The 30AX system, which Philips introduced in 1979, is an important landmark in the development of colour picture systems. With previous systems the assembly technician had to workthrough a large number of complicated setting-up procedures whenever he fitted a television picture tube with aset of coils for deflecting the electron beams. These procedures were necessary to ensure that the beams for the three colours would converge at thescreen for every deflection. They are no longer necessary with the 30AX system: for a given screen format any deflection unit can be combined  with any tube to form a single 'dynamically convergent' unit. A colour-television receiver can thus be assembled from its components almost as easily as a monochrome receiver. The colour picture tube of the PHILIPS 30AX system displays a noticeably sharper picture over the entire screen surface. This will be particularly noticeable when data transmissions such as Viewdata and Teletext are displayed. This has been achieved by a reduction in the size of the beam spot by about 30%. Absence of coma and the retention of the 36.5 mm neck diameter have both contributed to increased picture sharpness. Coma has been eliminated by means of corrective field shapers embedded in the deflection coils which are sectionally wound saddle types. The new deflection unit has no rear flanges. enabling uniform self-convergence to be obtained for all screen sizes. without special corrections, adjustments, or tolerance compensations. Horizontal raster distortion is reduced and no vertical correction is required. One of the inventions in 30AX is an internal magnetic correction system which obviates static convergence and colour purity errors. This enables the usual multiple unit to be dispensed with. together with the need for its adjustment !  New techniques have been employed to achieve close tolerance construction of the glass envelope. In addition, the 30AX picture tube incorporates two features whereby it can be accurately adjusted during the last stages of manufacture. One is the internal magnetic correction system. The other is an array of bosses on the cone that establish a precise reference for the axial purity positioning of the deflection unit on the tube axis and for raster orientation. During its manufacture, each deflection unit is individually adjusted for optimum convergence. The coil carrier also incorporates reference bosses that co-operate with those on the cone of the tube. ' Since every picture tube and every deflection unit is individually pre-aligned, any deflection unit automatically matches with any picture tube of the appropriate size. The deflection unit has only to be pushed onto the neck of the tube unit it seats. Once the reference bosses are engaged, the combination is accurately aligned and requires no adjustment for convergence, colour purity or raster orientation. With no multiple unit and a flangeless deflection unit, there is more space in the receiver cabinet. Higher deflection sensitivity means that less current is consumed, and consequently less heat is produced. This increases the reliability of the TV receiver again. 30AX means simple assembly. Any picture tube is compatible with any deflection unit of the appropriate size and is automatically self-aligning as well as being self-convergent.

The well-known 20AX features of HI-Bri, Soft-Flash and Quick-vision are maintained in the new 30AX systern.  In their work on the design of deflection coils in the last few years the developers have expanded  the magnetic deflectionfields into 'multipoles', Thisapproach has improved the understanding  of the relations between coil and field and between field and deflection to such an extent that  designing deflection units is now more like playing a difficult but fascinating game of chess than  carrying out the obscure computing procedure once necessary.

Furthermore :

Sound is produced by a nice speakerbox integrated in the cabinet allowing super bass sound allowed even by the tone controls.

On the front panel Right down side near the headphones jack lid there is a ambient light sensor which drives, in opportune, way the contrast tracking of the picture as a function of the light in the room were the tellye is running; more particularly to a control system for maintaining proper balance between room lighting conditions and the level of picture tube excitation in a color television receiver. More especially the present invention functions to increase contrast, intensity and chroma signal strength when the room lighting level increases to diminish these parameters when the level of room lighting decreases.

Conventional television receivers, of course, have manually operable controls by means of which a viewer may set the level of contrast, intensity, and chroma signal strength to what he feels to be an optimum level for given room lighting conditions. Under changed room lighting conditions, the viewer will obtain the optimum viewing situation by changing these manual controls to a new preferred level.

- Horizontal Beam Deflection  and high voltage generating circuits realized with Thyristors circuits.
       Numerous circuit designs for completely transistorized television receivers either have been incorporated in commercially available receivers or have been described in detail in various technical publications. One of the most troublesome areas in such transistor receivers, from the point of View of reliability and economy, lies in the horizontal deflection circuits.
       As an attempt to avoid the voltage and current limitations of transistor deflection circuits, a number of circuits have been proposed utilizing the silicon controlled rectifier (SCR), a semiconductor device capable of handling substantially higher currents and voltages than transistors.
       The circuit utilizes two bi-directionally conductive switching means which serve respectively as trace and commutating switches. Particularly, each of the switching means comprises the parallel combination of a silicon controlled rectifier (SCR) and a diode. The commutating switch is triggered on shortly before the desired beginning of retrace and, in conjunction with a resonant commutating circuit having an inductor and two capacitors, serves to turn off the trace switch to initiate retrace. The commutating circuit is also arranged to turn oft the commutating SCR before the end of retrace. 

In order to maintain optimum performance of the television receiver, it is desirable to provide a regulated direct current potential (B+) to the various circuits of the receiver. Numerous types of regulated power supply circuits have been used to provide the desired regulation. One such type is a switching regulator power supply.
Also, television receivers like the tv in this post utilizing line rate deflection systems of the type disclosed in U.S. Pat. No. 3,452,244 employing two bidirectional conducting switches require an input reactor between the source of B+ and the commutating bidirectional conducting switch to prevent short circuiting of the B+ during the commutating interval (i.e., when the commutating switch is turned on).

The set is build with a Modular chassis design because as modern television receivers become more complex the problem of repairing the receiver becomes more difficult. As the number of components used in the television receiver increases the susceptibility to breakdown increases and it becomes more difficult to replace defective components as they are more closely spaced. The problem has become even more complicated with the increasing number of color television receivers in use. A color television receiver has a larger number of circuits of a higher degree of complexity than the black and white receiver and further a more highly trained serviceman is required to properly service the color television receiver.
Fortunately for the service problem to date, most failures occur in the vacuum tubes used in the television receivers. A faulty or inoperative vacuum tube is relatively easy to find and replace. However, where the television receiver malfunction is caused by the failure of other components, such as resistors, capacitors or inductors, it is harder to isolate the defective component and a higher degree of skill on the part of the serviceman is required.
Even with the great majority of the color television receiver malfunctions being of the "easy to find and repair" type proper servicing of color sets has been difficult to obtain due to the shortage of trained serviceman.
At the present time advances in the state of the semiconductor art have led to the increasing use of transistors in color television receivers. The receiver described in this application has only two tubes, the picture tube and the high voltage rectifier tube, all the other active components in the receiver being semiconductors.
One important characteristic of a semiconductor device is its extreme reliability in comparison with the vacuum tube. The number of transistor and integrated circuit failures in the television receiver will be very low in comparison with the failures of other components, the reverse of what is true in present day color television receivers. Thus most failures in future television receivers will be of the hard to service type and will require more highly qualified servicemen.
The primary symptoms of a television receiver malfunction are shown on the picture tube of the television receiver while the components causing the malfunction are located within the cabinet. Also many adjustments to the receiver require the serviceman to observe the screen. Thus the serviceman must use unsatisfactory mirror arrangements to remove the electronic chassis from the cabinet, usually a very difficult task. Further many components are "buried" in a maze of circuitry and other components so that they are difficult to remove and replace without damage to other components in the receiver.
Repairing a modern color television receiver often requires that the receiver be removed from the home and carried to a repair shop where it may remain for many weeks. This is an expensive undertaking since most receivers are bulky and heavy enough to require at least two persons to carry them. Further, two trips must be made to the home, one to pick up the receiver and one to deliver it. For these reasons, the cost of maintaining the color television receiver in operating condition often exceeds the initial cost of the receiver and is an important factor in determining whether a receiver will be purchased.
Therefore, the object of this invention is to provide a transistorized color television receiver in which the main electronic chassis is easily accessible for maintenance and adjustment.
Metz: 70 Years’ of "made in Germany" quality

Customer-oriented and successful

Metz, one of the German electronic industry’s most independent and successful companies, celebrates its rich tradition as it enters its seventieth year. An amazing success story during a period when numerous well-known manufacturers had to concede to difficult market conditions and suspend business activity. In 1938 Metz began producing electronic equipment. During subsequent years Paul Metz led his company to a position of worldwide importance. The company currently focuses on three business areas: entertainment electronics, photo electronics and plastics technology. Numerous innovations shape both past and present and create a promising potential for the future. To date this has united the company’s development and production, which is still owner-led and based in Germany, guaranteeing a consistently high "made in Germany" standard of quality.

Back to the future


Metz was founded back in 1938. From this point in time, Paul Metz managed his company with untiring effort, always introducing new ideas to steadily grow the business. In 1947 he began producing radio sets. He expanded to other fields in the following years. And to this day Metz stands its ground successfully in the entertainment electronics, photo electronics and plastics technology sectors.

In 1993, Paul Metz died at the age of 82. Since then, his wife Helene Metz has continued with the company’s success story undetered. Entrepreneurial spirit combined with responsibility and committment to employees and society certainly characterise her management style; innovative ideas and excellent quality lay the basis for the positive evolution of a company. "My husband and I have always invested in the company and promoted its development. Independence was important to us. At the same time, we always attached great importance to excellently trained, highly motivated employees. And nothing will change these values in future."




Photo electronics: Metz flashguns attain world fame


In 1952, Paul Metz went in into the flashgun business and began marketing an emblematic trend-setting innovation in 1979 with the introduction of the worldwide single SCA adapter system which made it possible to attach Metz flashguns to cameras of all well-known brands and went on to establish Metz as one of the leading worldwide brands in this area. Since then, Metz flashguns have been exported to over 90 countries. The latest successful model was voted "the best flash unit in Europe" at the end of 2007. It was the world’s first flash to be equipped with a USB interface. The individual firmware for every version of the model can be easily updated via computer and internet by means of this interface.









Entertainment electronics: Metz - reliable trade partner

In 1955, Metz entered a business sector which later became its most important source of revenue - the production of television sets. This sector was further expanded in 1967 with the development and production of their own brand of colour TVs. Around this time, Metz began selective sales in the specialist consumer electronics trade, which forms a cornerstone of Metz’s service-oriented recipe for success to this day, ensuring the customer gets an additional service benefit as well as excellent products.
In 1990, the first TV set with Metz’s own 100-Hertz technology was introduced. The excellent, flicker-free image quality delighted both consumers and specialist publications.

In 1995, Metz came up with an innovation in the field of TV which continues to make the product line flexible, unique and successful to this day: The modular-built TV chassis was launched. From the turn of the Millennium, the first digital tuner was integrated. Another milestone came in 2005 with the introduction of their own-brand LCD-TV. Since then, flat screen TV sets with innovative technologies have been developed and produced at the company’s Zirndorf site with the "made in Germany" quality seal. At the same time the opportunity get into high definition television meant that in 2007 integrated HDTV modules were introduced into the Metz product range – unique worldwide – and which can also be retrofitted.
The Metz team always manage to weigh up the future realistically, as you can see from the current product range, which is constantly evolving and supplemented with new components that offer great marketing opportunities. Latest example is the implementation of HD panels with high resolution when operating in 100 Hertz DMC-technology and integrated hard disc recorder at IFA 2008. All TV sets of Metz offer the benefits of flexible retrofitting or exchanging of modules thanks to the Metz digital module concept, on which every chassis is based on.

Plastics plant: Metz - renowned partner for system solutions

Metz’s third line of business came about in 1957: The hi-fi furniture plant at Zirndorf went into operation making wooden cabinets for radio and TV sets. It expanded when it began plastics production in 1969. To this day, this sector represents another important constituent for Metz, especially in the production of its own high-quality TV cabinets. But renowned industrial partners also use the reliable production line at the German site with all its individual system solutions. The Metz plastics plant is the right place to go, from choosing suitable materials for a product concept, up to the provision of injection moulding forms. Complex techniques are used at the Zirndorf factory: interior gas pressure processes, thermoplastic foam injection moulding processes and ultrasonic welding and inmold technology, to name but a few.

Metz - traditional company on a solid foundation

After its formation, Metz went on to enjoy seven decades of continual success. At present, the company employs about 680 people, with a turnover of €129 million in 2007. The development, production and sales departments are grouped together on a 86,000 square-metre site. To this day, the company owes its positive development to the introduction of more innovative products and processes in all corporate divisions which play a large part making the products technically feasible and user-friendly.

"Our company stands on a solid foundation. Our planning for the next few years shows great promise; we will go on to further improve our core competences," says managing director Dr. Norbert Kotzbauer, who currently runs the company with Helene Metz. " Metz’s strength is the combination of excellent "made in Germany" quality, sure-fire future product concepts, clear marketing structures and absolute customer focus."
