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 ! !

PHILCO (BLAUPUNKT) MOD. ?? YEAR 1977.
























The PHILCO  (BLAUPUNKT)  MOD. ?? is  A 20 inches b/w portable television with 12 programs mechanical keyboard selection and potentiometric tuning search .

Was one of the models using a CHASSIS FROM BLAUPUNKT with a pretty rare thyristor horizontal output for a B/W set which was generally transistorized in 1977.
The massive demand for colour television receivers in Europe/Germany in the 70's  brought about an influx of sets from the continent. Many of these use the thin -neck (29mm) type of 110° shadowmask tube and the Philips 20AX CRT Tube, plus the already Delta Gun CRT . 
Scanning of these tubes is accomplished by means of a toroidally wound deflection yoke (conventional 90° and thick -neck 110° tubes operate with saddle -wound deflection coils). The inductance of a toroidal yoke is very much less than that of a saddle -wound yoke, thus higher scan currents are required. The deflection current necessary for the line scan is about 12A peak -to -peak. This could be provided by a transistor line output stage but a current step-up transformer, which is bulky and both difficult and costly to manufacture, would be required. 
An entirely different approach, pioneered by RCA in America and developed by them and by ITT (SEL) in Germany, is the thyristor line output stage. In this system the scanning current is provided via two thyristors and two switching diodes which due to their characteristics can supply the deflection yoke without a step-up transformer (a small transformer is still required to obtain the input voltage pulse for the e.h.t. tripler). The purpose of this article is to explain the basic operation of such circuits. The thyristor line output circuit offers high reliability since all switching occurs at zero current level. C.R.T. flashovers, which can produce high current surges (up to 60A), have no detrimental effects on the switching diodes or thyristors since the forward voltage drop across these devices is small and the duration of the current pulses short. If a surge limiting resistor is pro- vided in the tube's final anode circuit the peak voltages produced by flashovers seldom exceed the normal repetitive circuit voltages by more than 50-100V. This is well within the device ratings.
Here you can see a nice PHILCO Washing Machine.

Philco, the Philadelphia Storage Battery Company (formerly known as the Spencer Company and later the Helios Electric Company), was a pioneer in early battery, radio, and television production as well as former employer of Philo Farnsworth, inventor of cathode ray tube television. It is currently a brand of Philips.
Philco's rise to the top of radio makers was an amazing feat. While other makers like Atwater-Kent, Zenith Electronics, RCA, and many now-forgotten others (Freshman Masterpiece, FADA Radio, AH Grebe, etc.) sold many battery-powered radios in the early 1920s, Philco made only batteries, "socket power" units, and battery chargers. With the invention of the rectifier tube, which allowed radios to be operated from the wall socket, Philco knew their business was doomed, and decided in 1926 to get into the booming radio business. By 1930 they would sell more radios than any other maker and hold that first place position for over 20 years.
Philco built many iconic radios and TV sets, including the classic cathedral-shaped wooden radio of the 1930s (aka the "Baby Grand"), and the very futuristic (in a 1950s sort of way) Predicta series of television receivers.
Philco started experimenting with television in the early 30s and financed for a while the experiments of Philo T. Farnsworth, considered by many as the “father of television.”An experimental TV station was licensed to Philco in 1931, one of the first all-electronic television ;
Granting of such experimental broadcasts by the FCC was common practice at that time, as television took its first tentative steps in New York City, Schenectady, and Philadelphia. While the rest of the country remained oblivious to the new medium, viewers in those cities bought several thousand sets to watch the limited schedule of programs transmitted by pioneering broadcasters of the East Coast who jumped at the opportunity to go from experimental to commercial television broadcasting.
By 1937, Philco was using an experimental 441-line television system which utilized a 12” television receiver—a direct, but bulky competitor to David Sarnoff’s RCA 12” set.
Along with the stations that would become WNBC-TV and WCBS-TV in New York City and WRGB-TV in Schenectady, WPTZ-TV, Philco Corporation's station in Philadelphia, gravitated to sports to fill air time.
On October 5, 1940, when there were about 700 sets scattered throughout the Philadelphia area, Philco broadcast the University of Pennsylvania's Quakers 51-0 victory over the University of Maryland at Franklin Field.

Today, the Philco brand name is carried by several different companies and holding groups throughout the world.

Philco International
In 1974, 13 years after purchasing the Philco Corporation, Ford begins divesting part of the Philco business by selling the Consumer Electronics Division to GTE Sylvania. Three years later, Philco International is purchased by White Consolidated Industries (WCI). In 1986, Philco and WCI are purchased by AB Electrolux of Sweden. And, in 1988, Philco finally moves out of Philadelphia to Pittsburgh, to join other WCI affiliates.
Itautec-Philco S.A.
In 1989, Philco-Brasil is bought by the group Itaúsa, part of Bank Itaú. Most of its plants are centered around three plants in Manaus for the manufacture of TV sets, video cassettes, fax machines, printers, and PC boards.
Philco-Argentina
It is owned by Jorge Blanco Villegas and has a plant in Ushuaia, Tierra del Fuego. It manufactures mostly Semi Knock Down (SKD) type components, i.e., fabrication of pre-assembled PC boards and components. The German company VDO imported Philco-Argentina auto radios into Brazil for a while¾but with little success.
Philco-Italia S.P.A.
During the 70s, Philco-Italia became part of Bosch-Siemens and was subsequently acquired in 1987 by the Gruppo Merloni with Felice Colombo as president. It currently manufactures refrigerators and air conditioners in northern Italy having distributors in all 5 continents, Philco G.B. Ltd. in England, Philco Trading in Egypt, Bendix Unit B1 in Australia, among others.


Blaupunkt GmbH is a German manufacturer of electronics equipment, noted for its home and car audio equipment. It was a 100% subsidiary of Robert Bosch GmbH until March 1st, 2009 (Date of closing) when its Aftermarket and Accessories branch including the brand name were sold to Aurelius AG of Germany for an undisclosed amount. Founded in 1923 in Berlin as "Ideal", the company changed its name to "Blaupunkt" in 1938, German for "blue point" or "blue dot" after the blue dot painted onto its headphones that had passed quality control. After the Second World War, Blaupunkt moved its headquarters and production to the city of Hildesheim.

Today the majority of Blaupunkt products are manufactured overseas, with large manufacturing centers in Tunisia (speakers) [WTF !!! !!!] and Malaysia (speakers and electronics) [arrrrgggghhh!].
During the 1960 and 1970s, Blaupunkt had become the leading German manufacturer for car radios and car audio equipment. Blaupunkt was involved in the development of the Autofahrer-Rundfunk-Informationssystem traffic-information system for car radios, and provided this feature on their German-market car radios from the late 1970s. The company attempted to have ARI used in the USA but had only a few radio stations per major city involved.
