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 23K45 YEAR 1968.




The  PHILCO  23K45 is a   23 inches television set with tubes technology and VHF and UHF selectors transistorized type.

The set was one of the first PHILCO tv models  using PCB circuit layer for the chassis circuitry.

It has a 2 way audio channel.


On front of the screen there is a dark heavy glass.

Here you can see a nice PHILCO Washing Machine.


The B/W Tubes Television set was powered with a External Voltage stabiliser unit (portable metal box) which relates to voltage regulators of the type employed to supply alternating current and a constant voltage to a load circuit from a source in which the line voltage varies. Such regulators are frequently provided employing saturable core reactors and condensers connected in circuit...  in such manner as to provide a plurality of variable voltage vectors which vary in different senses, as the line voltage varies, but which add vectorially in such manner that their vector sum remains substantially constant upon variations in line voltage, for providing automatic voltage stabilization of single or multiphase A. C. circuits where the supply voltage and frequency are subject to variation above and below normal value and where the load is subject to variation between normal limits.
voltage stabilization
is automatically effected by the provision of an inductive pilot control device which is adapted to provide two excitation supply voltages for producing excitation or satuation of two magnetic circuits of a reversible booster transformer unit or units and diversion of flux from one magnetic circuit to the other, the booster unit being energized by primary windings from the A. C. supplysystem and being provided with a secondary winding or windings connected between the supply system and the corresponding inain or distribution circuit and in series therewith, through which a corrective boost voltage is
imrorjiiced into the circuit under the influence of the pilot control device, of an amount equal to that of the supply voltage fluctuation which initiated it and appropriate in polarity and direction for restoring the voltage to normal value and providing automatic stabilization of the circuit voltage against supply voltages which fluctuate above and below normal value.

The pilot control device which may be employed singly or may comprise three units or their equivalent when applied to multiphase supply systems comprises a pair of closed magnetic circuits or cores constructed of strip wound magnetic material or stacked laminations, the two
circuits forming a pair being constructed of materials possessing dis~similar magnetic characteristics when jointly energized by identical windings in series or by a collective primary winding, the said magnetic circuits being suitably proportioned to provide equal fluxes when ener-
gized at normal voltage.

The pilot control device is provided with a main and an auxiliary secondary winding or group of windings, the main secondary winding or windings being adapted to provide a voltage representing the difference in the fluxes of the two circuits to which it is jointly associated, while
the auxiliary secondary winding embraces only one circuit, preferably that subject to the least amount of flux variation. Either of the windings consists of two equal sections or in effect a double winding with a center tapping to which one end of the single winding is connected.

The voltage in the single secondary winding of the pilot device becomes directionally additive to that in one half of the tapped secondary winding and substractive in respect to that in the other half. When the supply voltage is normal the voltage provided by the single secondary winding is zero, since there is no difference of flux in the two magnetic circuits, and the two excitation voltages
produced in the halves of the other secondary winding are equal and when connected to the two excitation windings of the booster units, do not produce any diversion of flux between the two circuits or sets of circuits in the magnetic system of the booster transformer unit become equal, and since the series winding on the booster unit is arranged to provide a voltage due to the difference of
the fluxes in its two magnetic circuits or sets of magnetic circuits, no corrective voltage is introduced into the main circuit by the booster. If, however, the supply voltage varies from normal the pilot control device provides a voltage across the one secondary winding due to the difference in the fluxes of the two dis-similar magnetic circuits of which it is comprised, which voltage is combined with thosc in the halves of the other secondary winding to provide two excitation voltages which vary complementarily to each other as the supply voltage fluotuates, and cause a transference of flux between the two
circuits or groups of circuits in the booster unit and automatically provide a corrective boost voltage in the main circuit in which the series winding of the booster transformer is includcd of a value equal to that of the variation in supply voltage which initiated it.
The pilot device may be arranged in various ways, forboth single phase and multiphase operation, as exemplified by the constructions hereinafter more fully described.Similarly, numerous arrangements of the booster transformer unit are possible, some of which are hereinafter described in detail. The booster transformer unit embodies thc principles of the inductive devices described in my co-pending Application No. 411,189, filed February 18, 1954.

As an alternative to the provision of an auxiliary secondary winding on the pilot control device this may be
replaced by an independent or external source of supply,which may be either subject to or independent of supply voltage variation, provided such supply may be arranged with a center tapping if required.

Feed-back arrangements may be employed for providing compensation against voltage drop due to the effects of load in various ways. These are preferably providedon the booster transformer unit and may comprise a current transformer in one or more lines of the main circuit,
the secondary output of the transformer being rectified and arranged to energize an additional excitation winding on the booster transformer unit which in clfect increases the amount of the corrective boost voltage as the load increases.





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.
