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 ! !

BRIONVEGA MIZAR 2A 24" YEAR 1977.














THE BRIONVEGA  MIZAR  2A  24" IS A 24 inches B/W television from BRIONVEGA.
Tablemodel, low profile (big size), wooden type.
Brionvega Mizar 2; 24" b/w TV with CCIR B/G standard VHF-/UHF tuner, tinted screen shield.

In the era of time were the majority of interest was around the color television, the market was even demanding for B/W sets.

This set has no remote and only push button program preselection and potentiometric tuning search.

In these tuning units, the working voltages of the capacity diodes in the tuning circuits are recorded once a precise tuning to the desired frequency has been performed. A potentiometer tuning system has great advantages over the formerly used channel selectors operating with mechanically adjustable capacitors (tuning condensers) or mechanically adjustable inductances (variometers), mainly because it is not required to have such great precision in its tuning mechanism.

Tuning units with bandswitches formed of variable resistances and combined with interlocking pushbuttons controlling the supply of recorded working voltages to capacity diodes are known. Channel selection is accomplished by depressing the knobs, and the tuning or fine tuning are performed by turning the knobs. The resistances serving as voltage dividers in these tuning units are combined into a component unit such that they are in the form of a ladderlike pattern on a common insulating plate forming the cover of the housing in which the tuning spindles and wiper contacts corresponding to the variable resistances are housed. The number of resistances corresponds to the number of channels or frequencies which are to be recorded. The wiper contact picks up a voltage which, when applied to the capacity diodes determines their capacitance and hence the frequency of the corresponding oscillating circuit. The adjustment of the wipers is performed by turning the tuning spindle coupled to the tuning knob. By the depression of a button the electrical connection between a contact rod and a tuning spindle is brought about and thus the selected voltage is applied to the capacity diodes. Since the push buttons release one another, it is possible simply by depressing another button to tune to a different receiving frequency or a different channel, as the case may be.

 Moreover, using this arrangement, the only indication--during adjustment--of which channel is selected is by station identification.
For many years, mechanical turret tuners have been commonly employed in television receivers to select the VHF channels and a second rotary or continuous tuner has been used to select the UHF channels. For most television receivers, this requires two different channel selection knobs; and the tuners themselves are relatively bulky and require a relatively large amount of space within the television receiver cabinet. Because of the nature of these tuners, it also is necessary to locate them directly behind the front level panel of the receiver, which imposes significant restrictions on the cabinet design and the arrangement of parts within the cabinet, reducing the flexibility of design which would be possible if such tuners could be eliminated.

Some mechanical tuners are equipped with programmable switches to permit them to be used to select either a UHF or a VHF channel at a tuner position by programming the tuner for the local area where the television receiver is to be used. The disadvantages of the cumbersome mechanical tuners, however, are not overcome. Instead, the tuner is made even more complicated by such an arrangement.

It is desirable, and in the U.S./Europe it was  necessary, to effect selection of the UHF and VHF channels in a comparable manner. When such tuning compatibility is imposed, significant problems are encountered in providing a mechanical turret-type tuner having detented positions for all of the possible UHF channels which must be accommodated for television receivers capable of operating in any given locality in which the receiver is capable of receiving transmitted television signals. UHF turret tuners with detent tuning selection for each of the 70 possible UHF channels are difficult and expensive to manufacture, and even the display of all of the UHF channel numbers in a manner which is compatible with the display for the much smaller number of VHF channels is difficult to accomplish.
The introduction of voltage-variable capacitor or varactor tuners for the VHF and UHF bands to which a television receiver can be tuned has opened the way for electronic tuning of television receivers. This replaces the cumbersome mechanical turret tuners and allows greater flexibility in the design of the channel selection panel and in the location of tuner parts within the receiver cabinet. Even so, if the receiver is to be made capable of individual selection of any one of the 70 UHF channels in addition to the VHF channels, it has been necessary to provide a large number of individual tuning components. For example, in many prior art electronic tuner control circuits, it has been necessary to provide a separate tuning potentiometer for each of the 70 UHF channels if full capability of UHF channel selection is desired. This results in a relatively expensive tuner configuration requiring a large number of parts.

The commands are all locate right side and the tuning drawbar is a box which can be pulled out to tune channels.


Even this set has his design BRIONVEGA style.

NOTE The base of the tv and the envelope of the frontend and the commands buttons design style.


Brionvega is (was) an Italian electronics company, established in Milan in 1945.

Good design is no longer simply for an "elite" but is demanded by a far wider audience interested in continuous development.With so many designs and products available, how is it possible to distinguish a truly outstanding design from one that is simply trendy. World famous designers: Hannes Wettstein, Mario Bellini, Richard Sapper, Marco Zanuso, Castiglioni brothers and Ettore Sottsass, have tried to come up with the answer to what constitutes the perfect design. In finding inspiration, when designing for Brionvega, these people look beyond every day fashion and look for examples which are outstanding in their beauty. They also pay attention to people's attitude and how they relate to everyday objects.


Historically speaking, Brionvega is one of the most famous radio and Television manufacturers, thanks to its products, born from the collaboration with well-known design firms. Over the years, from its establishment, Brionvega has made some industrial design corner-stones, such as the radio "cube" TS502 from 1963, the Algol and Doney portable TV, and the radio-phonograph RR126.

The BRIONVEGA stylish design is well recognized around the world for it's particularity.
The television here in collection The BRIONVEGA  MIZAR  2A  24"  is a clear example of that style.
