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.

Every CRT Television saved let revive knowledge, thoughts, moments of the past life which will never return again.........

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 ! !

SINUDYNE EOS YEAR 1982.



The SINUDYNE EOS is a portable 16 inches color television with 32 programs and PLL synthesized tuning search with ITT featured tuning system and was called by SINUDYNE the TELECOMPUTER.
Television receivers of the type under consideration frequently include a frequency synthesizer for tuning the receiver's local oscillator to the nominal carrier frequency of a selected television channel. Generally, the frequency synthesizer compares the local oscillator frequency to a reference frequency associated with the selected channel, and then varies the local oscillator frequency until it equals the reference frequency. Presumably, the receiver will now be correctly tuned to the selected channel.
This method of tuning the receiver relies, of course, on the frequency of the incoming television signal being equal to its nominal or standard frequency. It has remote and a local keyboard which is almost replicating all basic functions of the set. Since the tuning system operates on the local oscillator frequency, there is no dependence on individual characteristics of the varactor other than the requirement that the tuner drive system must be capable of tuning the varactor tuner over all channels.This invention relates to a digitally controlled, electronic tuner that can be tuned to any of several different channels at different frequencies and which includes an automatic fine tuning (AFT) circuit to adjust the tuning precisely when the frequency to which the tuner is tuned is within a predetermined frequency range close to the exact desired frequency. In particular, the invention relates to a television signal tuner for a receiver having an AFT circuit to maintain the tuning at a selected frequency according to one of the available channels and further including means to overcome the effect of the AFT circuit when it is desired to shift the tuner to a different channel.

The set is entirely developed in ITALY in Sinudyne with a unique modular chassis type.

Components and Semiconductors parts are naturally from PHILIPS - MOTOROLA -SIEMENS.

Was first SInudyne TV set featuring the Motorola TDA3300 A bipolar linear PAL colour decoder, with provision for multi-standard operation, on-screen display and an automatic C.R.T. current set-up system, is described. This device uses a 40 pin DIL plastic package.This invention relates to a system for stabilizing the cathode emissions from an in-line gun cathode ray tube and for maintaining the ratio of the beam currents in the cathodes within a predetermined desired range. The system includes a subsystem that can be linked to each of the cathodes of an in-line gun or delta gun CRT comprising means for interrupting the flow of a video signal to the cathodes of a cathode ray tube; means for imposing a predetermined test signal on each or any of the cathodes; means for detecting the actual current flowing to each or any of the cathodes of a cathode ray tube independently of the others; means for sampling the actual current; means for detecting the difference between the sampled actual current and a predetermined, desired current; means for developing a signal representing the difference, if any, between the sampled actual current and the predetermined current; and means for using the differential signal to drive the actual current to the predetermined value.Motorola's third generation PAL decoder system (Chroma III) employs a single 40 -pin i.c., type TDA3300. Amongst the features of this i.c. are low dissipation, typically 600mW, with a single 12V supply; a patented 90° phase - shift system requiring no adjustment; and direct inputs for on -screen (data, TV games, etc.) displays, with a complementary fast blanking input. Of particular interest is the beam limiting and automatic black -level adjustment system, the latter making it unnecessary to incorporate preset controls to set up the black level. These arrangements rely on three high -voltage transistors to monitor the beam currents, providing feedback signals for the i.c.  If the reference voltage is exceeded, the beam current limiting action comes into operation, reducing the contrast. The system has been designed to enhance the set's video and digital signal handling capability. During the flyback time the feedback input impedance rises, activating a further internal comparator. This compares the tube's cut-off current (a hot cathode doesn't cut off completely) with another internal reference voltage. The resultant signal is integrated and added to the output (at the output clamp) to provide the automatic black -level correction. Readers may recall that a similar idea, using discrete circuitry, is employed in certain B and 0 colour chassis. The advantage is that the black level is held constant throughout the tube's life, with no grey scale drift.
In the past, it has been generally necessary to provide separate drive controls for each of the three signal paths in a color video display. Further, inasmuch as the respective guns of a CRT picture tube age differently, it has been necessary to adjust the drive controls of the CRT throughout its life, particularly during the first twenty-four hours. In this respect, it has been necessary to "burn-in" the set to stabilize operation of the guns such that a final manual adjustment could be made of the respective gain controls.
In this regard, several integrated circuits for television receivers have introduced automatic setting of the CRT operating point, or its dc (black) reference level. However, there has heretofore been no provision for automatic setting of the video gain or contrast (gray) operating point.
Further, the brightness control of a television or video display receiver is usually accomplished by shifting the bias or dc reference level of the video display. This operation has the effect of changing both the average luminance of the display as well as the contrast ratio of the picture. In like manner, the contrast control is normally an amplitude control, the operation of which will also affect average luminance as well as the contrast ratio. In a color television or data display system, saturation and hue may also be affected. Previously, there has been no provision for compensating the brightness control signal such that the picture black level remains unaffected by the contrast control signal.

These sets were offering ultra bright pictures with very superb colors and sharp pictures.

This series and earlyer types was advertised with The slogan of SINUDYNE in the 80's , and it was "SINUDYNE COLORE STUPORE ! " and this was meaning " SINUDYNE COLOR ASTONISHMENT " in English.


SINUDYNE was an Italian manufacturer of radio and television sets.

It was founded in 1946 SEI-Società Elettronica Italiana S.p.A., by two mates : Antonio Longhi and Bruno Berti, and they started manufacturing radio apparates with tubes.

In 1954 the started producing television sets which was in the 70's theyr primary activity.

In 1959 the production was transferred at Ozzano dell'Emilia near Bologna.

SINUDYNE have had a good success in Italy were it have had large diffusion and lots of service centers because a good quality of product and design.

In 1983 SINUDYNE realized the first Italian Digital Television employing the ITT DIGIVISION Technology

HERE Today I'm showing one of the Advanced models of DIGITAL TELEVISION From SINUDYNE the HQ Vision Digi-System models series.

SINUDYNE was in the 1980's and in the 1990's even importer of brands like NORDMENDE and
ORION which is the manufacturer of the television here shown in collection.

SINUDYNE was even known for it's product design which was quite remarcable some times.

The slogan of SINUDYNE in the 80's was "SINUDYNE COLORE STUPORE ! " and it was meaning " SINUDYNE COLOR ASTONISHMENT " in English.

In 2002 SINUDYNE was aquired by another Italian group called Merloni which introduced productions of appliances like air conditioning clima systems.

In 2003 SINUDYNE started marketing LCD (Crap) displays.

In 2006 SINUDYNE closed his production factory landing to fail !!

TODAY'S SINUDYNE IS NO MORE .................. DEAD !
