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.

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 ! !

The chassis is a little center placed PCB with all part on it.
  The whole board is built around the CD5151CP. Excluding passives this chip seems to have everything needed to build a TV receiver : video and audio intermediary frequency, tuner frequency control, automatic gain control, FM detector for audio, detection of synchronization pulses and horizontal and vertical deflection oscillators and drivers. There is also a TA8164P, which is a radio tuner IC. The CD5151CP already has integrated FM decoding circuitry. It may have something to do with the SECAM-L standard.


The UTC AN5151 is a monolithic integrated circuit containing
all stage for the VIF,SIF and deflection of television receivers.
 GENERALLY, the operation of a conventional television receiver includes two main components. First, the receiver receives the incoming television signal in radio frequency (RF) and converts the incoming RF signal to an intermediate frequency (IF) signal. Then, the receiver converts the IF signal to a video baseband signal and an audio baseband signal. The baseband signals are coupled to appropriate video and audio decoders to generate the display video signals (e.g. RGB or only luminance for b/w) or sound. In general, the conventional television receiver includes a tuner for receiving the input RF signal and converting the RF signal to an IF signal by one or more frequency conversions. The frequency conversions are generally implemented as single or dual super-heterodyne conversions. In conventional television receivers, the intermediate frequency is dictated by the geographical area the receivers are to be used.
*Hight integrated technology makes it possible the integration of
video IF circuit tuner AFC circuit sound. IF circuit and
deflection.-jungle circuit on one single chip.
*supply voltage range:8V to 12V

Also, the conventional television receiver also includes a channel filter and a demodulator for converting the IF signal to video and audio baseband signals. The channel filter is typically a discrete filter implemented as a SAW (Surface Acoustic Wave) filter see pictures. The shape of the SAW filter is designed specifically for the format (analog or digital TV) and the television standard (NTSC, PAL or SECAM) of the television signals being received. The demodulator is typically a dedicated component and designed specifically for a predetermined television signal format and a predetermined television standard. For analog television signal reception, the demodulator is a VIF/SIF module. The VIF/SIF module provides a video output called CVBS (Composite Video Baseband Signal) and audio outputs, such as MPX or A2.

*IF Amplifier, IF AGC
*Video Amplifier, Video Detector
*Noise Canceller, Forward RF AGC
*Tuner AFT,SIF Amplifier
*Sound Detector, sync separation
*Vertical oscillation trigger and driver
*Horizontal oscillation driver and AFC

The circuit here shown is an extreme example of semplification of a b/w tv receiver in accordance of above statements.

The TA8164P is AM/FM Tuner (FM F/E + AM/FM IF) IC, which is designed for AM/FM monaural radio. Combining with the TA7368P (Mono PW IC), a suitable monaural AM/FM radio system is able to be constituted.
Common output for AM/FM Switch over between AM/FM mode is possible with one- wake switch
