Richtige Fernseher haben Röhren!

In Brief: On this site you will find pictures and information about some of the electronic, electrical and electrotechnical Obsolete 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.

- The search this blog feature provided by Google is a real search engine. If you're pointing particular things it will search IT for you; or you can place a brand name in the search query at your choice and visit all results page by page. It's useful since the content of the site is very large.

Note that if you don't find what you searched for, try it after a period of time; the site is a never ending job !

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 ! !

VIDIKRON TGS100 CHASSIS TGS100 INTERNAL VIEW.


































































































































































VIDIKRON TGS100   CHASSIS TGS100  is developed on a  multi board basis, on left side all power and signal parts composing the receiver, on right sisde the power supply unit panel.

Is well organized and easy to look for inspection.

On the Front side all convergence sections and controls.

The apparatus isn't that bad except for some self burning of capacitors in the line deflection circuits.

The tuning is realized with PLL synthesizer type located on the bottom chassis.




Here some circuits descriptions:

TDA3803A Stereo/dual TV sound decoder circuit:


GENERAL DESCRIPTION
The TDA3803A is a stereo/dual TV sound decoder circuit with static switching for processing two AF signals in TV and
VCR equipment. The LOW/HIGH static switching signals control the AF output selector. Two operational amplifiers
perform bandpass filtering of the identification signals.
Features
· Amplification of the two AF input signals by integrated operational amplifiers
· Low distortion stereo de-matrix
· All operational amplifiers offset compensated
· De-emphasis with operational amplifiers, preferably applied to the output terminals
· Two output ports each with two channels for headphones and loudspeakers
· Dual sound information at one port, each port individually switchable from sound I to sound II and sound II to sound I
· Mute function; while mute is active, it is possible to connect an external mono AF input signal to pin 10 appearing at
pins 20 to 23.
· Identification without additional signals (horizontal etc.)
