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 ! !

GBC MOD. 7319 YEAR 1976.



This set from GBC has 19 inches B/W screen with front glass and 8 programs keyboard with potentiometric tuning search.

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 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.

The set is tubes based even if it's made in 1976 where majority are semiconductors based.

The set has a color burst killer button feature to lock the broadcasted color burst to avoid disturbances on the picture and this because at the time many transmissions were already in color.




GBC is a commercial brand with a long tradition and solid experience. It history begins in 1958, when Gian Bruto Castelfranchi (G.B.C.) established the company, with the aim of conquer the market.GBC is the acronym for Gian Bruto Castelfranchi, who founded the company in 1958 in order to commercialize instrument accessories and related material.
It is his son Jacopo, however, who made GBC the biggest company in Italy for the commercialisation of electronic materials and devices.

Jacopo joins his father's company in 1946, starting to increase the number of represented products and expanding in the field of electronic components, tubes, passive components and various equipment such as tape recorders and turntables.

The company expands and diversifies and in 1957 the Selezione di Tecnica Radio TV periodical is born, for which is created the J.C.E., Jacopo Castelfranchi Editore who was also the editor
of a monthly Magazine "IL CINESCOPIO" with his technical director Amadio Gozzi.

Not to be confused with the Selezione Radio magazine, published from 1951.

In 1962 the head office is transferred to Cinisello Balsamo owing to a shortage of space.
In 1970, the magazine changes its name to Sperimentare Selezione di Tecnica Radio TV.
In 1970 it becomes a Sony distributor for Italy and it later creates a joint venture with it.
The sales points in Italy reach maximum expansion with over 150 shops.
GBC also designs and creates its own high-fidelity stereo systems and televisions.
In these years, GBC also commercialises assembly kits branded “High kit” and “Amtron”.
In the next few years, it also becomes an importer for Bang&Olufsen, Sinclair and Goldstar.
GBC is sold in 1980.

With these words we could define Kon.El.Co. S.p.A. The history of the society in fact is recent, but the competence and the experience baggage that this company is able to guarantee, defines this reality as a reliable distributor with a long commercial tradition. Founded in 1994, Kon.El.Co. S.p.A. developed immediately, earning the concession of well-known commercial brands. Subsequently the company has become a S.p.A. and since then has obtained great results, always more and more rewarding, that today define Kon.El.Co. S.p.A. as one of the leader society in the electronic branch. Since the beginning, GBC brand accompanies the success of Kon.El.Co. S.p.A., constituting the most important commercial project of the company.
