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 ! !

WEGA COLOR 3016 YEAR 1973.

The WEGA COLOR 3016 is a 26 inches (66cm) color television from WEGA an extint German manufacturer.

It's white design was a special edition in the 70's for some stylish living room models.

It has 8 programs with electric push buttons and manual potentiometric tuning search type in a drawbar, NO REMOTE.

This set is the first color television from WEGA entirely based on semiconductors technology and a 110° degree DELTA CRT TUBE.
It has a  picture tube apparatus employing the so-called delta gun  shadow mask  The present invention relates to a color television picture tube  type color cathode-ray tube which is provided with three electron guns positioned respectively at the vertices of an equilateral triangle, " the so-called delta gun  shadow mask ".

To obtain a fine color picture on the screen of the cathode-ray tube of this type, the following requirements should be satisfied that the electron beam is emitted from each electron gun onto the center of each corresponding phosphor dot on the screen of the cathode-ray tube, the purity of colors is high and the electron beams are converged onto a group of phosphor dots.
These requirements can be comparatively easily satisfied in the case of the cathode-ray tube with a spherically formed screen, whereas it is difficult to satisfy the requirements in the case of a narrow-necked, wide-angle deflection cathode-ray tube. The wide angle deflection cathode-ray tube is advantageous in practical use because the distance between the electron guns and the screen is small and the screen is almost flat with a curvature approximate to that of a flat surface; however, it is necessary to control the electron beams so that the electron beams may be emitted exactly onto the 3-color phosphor dots on the screen because the incident angle and distance of the electron beams which reach the phosphor dots on the screen have the values proper to respective phospher dots.

The  Horizontal Beam Deflection  and high voltage generating circuits are realized with Thyristors circuits. 
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.       Numerous circuit designs for completely transistorized television receivers either have been incorporated in commercially available receivers or have been described in detail in various technical publications. One of the most troublesome areas in such transistor receivers, from the point of View of reliability and economy, lies in the horizontal deflection circuits.

       As an attempt to avoid the voltage and current limitations of transistor deflection circuits, a number of circuits have been proposed utilizing the silicon controlled rectifier (SCR), a semiconductor device capable of handling substantially higher currents and voltages than transistors.
       The circuit utilizes two bi-directionally conductive switching means which serve respectively as trace and commutating switches. Particularly, each of the switching means comprises the parallel combination of a silicon controlled rectifier (SCR) and a diode. The commutating switch is triggered on shortly before the desired beginning of retrace and, in conjunction with a resonant commutating circuit having an inductor and two capacitors, serves to turn off the trace switch to initiate retrace. The commutating circuit is also arranged to turn oft the commutating SCR before the end of retrace.

WEGA (English pronunciation: /ˈveɪɡə/) was a pioneering German audio and video manufacturer, manufacturing some of Germany's earliest radio sets.


WEGA was founded as Wuerttembergische Radio-Gesellschaft mbh in Stuttgart, Germany in the year 1923. In 1975, it was acquired by Sony Corporation. At this point, they were known throughout Europe for stylish and high-quality stereo equipment, designed by Hartmut Esslinger amongst others. The WEGA brand continued to represent Sony quality for thirty years until 2005 once LCD displays superseded the company's Trinitron aperture grille based CRT tube models.
Starting in 1998, Sony released a television line called FD Trinitron WEGA, a flat-screen television with side-mounted speakers and a silver cabinet. At its release, the television was considered revolutionary in its performance and minimalist design; the WEGA was a success in the marketplace to the point that almost every flat-screen CRT television has copied its design.[citation needed]
Sony marketing materials for the television state that the FD Trinitron WEGA was named after the main star in the Lyra constellation (usually spelled 'Vega' in English), and made no reference to the original WEGA firm. Many products sold by Sony after its acquisition of WEGA shared much design language with the television, notably the rather minimalist styling and silver metallic finish.[original research?]
Although other European languages swap the V and W from German, WEGA is still pronounced "Vega".
Sony has also used WEGA to advertise flat-screen televisions with newer technologies than CRT. Their flat-panel LCD TVs were branded LCD WEGA until summer 2005 when they were rebranded BRAVIA (early promotional photos exist of the first BRAVIA TVs still bearing the WEGA label). Sony's rear-projection televisions, either SXRD (Silicon X-tal Reflective Display) or LCD-based, were branded as Grand WEGA until Sony discontinued production of rear-projection sets.

Die Firma hat schon beim frühen Start finanzielle Schwierigkeiten und bringt erst sehr spät (1936) auch Superhets auf den Markt. Es bleibt ein mittelständisches Unternehmen - auch nach dem Krieg - und gelangt 1975 an SONY. 1923: Würtembergische Radio-Gesellschaft mbH, Stuttgart - ab 1952 Fellbach bei Stuttgart.
1956: Wega Radio GmbH;
1975: Verkauf an Sony.
Radios: 1924-1975 (1979).

Am 10. Mai 1924 erhält Stuttgart einen MW-Rundfunksender mit 0,25 kW Leistung. Gegen Ende 1924 übernimmt der Fotokaufmann mit Radio-Fotohandelsgeschäft, Hugo Mezger, die Würtembergische Radio-Gesellschaft mbH, Stuttgart. Sie ist 1923 durch Ferdinand Hammer und Fritz Müller gegründet (24.1.1924 Registereintrag), doch schon konkursreif.

Noch 1924 bringt Wega den R IIa auf den Markt und mit dem R IIIa einen Batterieempfänger, der später wegen seiner eleganten Aufmachung im Berliner Reichsmuseum zur Ausstellung kommt. Der Apparat verbleibt dort bis zur Zerstörung des Museums, da sein geschlossener Aufbau als Steilpult mit ovalem Sichtfenster als sehr fortschrittlich gilt.

Metzger kauft Mitte der 20er Jahre die Süddeutsche Radio-Zentrale Willi Diettrich . 1926 übernimmt er den Markennamen Wega (nach dem Stern Wega) als Firmennamen .

Wegen dem Gleichstrom-Lichtnetz von Stuttgart sind erste Netzempfänger für Gleichstrom vorgesehen, wobei eine interne oder externe Glühlampe als Vorwiderstand dient. Erst ab 1936 fabriziert Wega auch Superhets. Den Anfang bilden die «Super-Koffer WSK» und «Phono-Super-Koffer WSKP». 1937 folgen diverse Heim-Super. Dabei präsentiert Wega z.B. Modell 648 von 1938 mit den Aussagen: «Ein vollwertiger Sechskreis-Super zum bisherigen Preis eines Zweikreisers!» und folgert dann «Warum überhaupt Super? - Hand in Hand mit der Zunahme von Zahl und Energie der Sender in allen Ländern wachsen die Schwierigkeiten im Fernempfang. Insbesondere werden an die Trennschärfe des Empfangsgerätes die höchsten Anforderungen gestellt. Hier kann, wie die Erfahrungen in der ganzen Welt zeigen, nur der Super auf die Dauer das Feld behaupten».

Wie wahr, doch erst gegen Ende der 30er Jahre kommt Wega mit dieser Erkenntnis, mindestens fünf Jahre zu spät.

Trotz den Sprüchen «Die Welt im Heim durch Wega 648W» oder «Der Wega-Super 648W ist eine Sensation» gelingt es dem Unternehmen nie, eine grössere Bedeutung zu erlangen. Wenn eine heutige Radioprospekt-Sammlung im Umfang von 30 nur Deutschland enthaltende 7-cm-Ordnern voll Unterlagen für Wega nur einen Prospekt und vier Bedienungsanleitungen enthält, kann die Firma nicht viel Direktwerbung bei den Händlern betrieben haben. Die Firma musste so relativ klein bleiben. Mitte 1939 beschäftigt das Unternehmen ca. 250 Personen .

Während den Kriegsjahren kann Wega neben der Kriegsproduktion auch Exportgeräte bauen. Trotz mehrfacher Bombentreffer bleibt der Schaden gering; 1946 entsteht ein Wega-Allstrom-2-Kreisempfänger, der eine Stückzahl von gegen 15'000 erreicht. Nun führt Dr. Motte, der Schwiegersohn von Hugo Mezger und Mitinhaber der Firma den noch immer in Familienbesitz befindlichen Betrieb.

Nach der Währungsreform baut Wega einen Allstrom-1-Kreiser (213GW) im Holzgehäuse und einen 6-Kreis-4-Röhren-Allstromsuper (864GW) im Bakelitgehäuse.

1949 hat der 4-Kreis-Allstromsuper «Regina» besonderen Erfolg.

1952/53 bezieht Wega den Fabrikneubau in Fellbach.
Trotz diesem relativ langen Bestand der Firma entwickelt Wega bis 1950 nur gut 80 Rundfunkempfänger, gewinnt in den 50er- und 60er Jahren aber dennoch etwas mehr Bedeutung, was eine gute Dokumentation der Geräte durch Schaltpläne unterstreicht.

Dann zeigt sich folgender Endspurt:
1965 lässt Wega Steuergeräte mit Röhren/Transistor-Bestückung im Design-Look entwicklen. Hartmut Esslinger gestaltet die Apparate. Ende der 60er Jahre ist Verner Panton für das Design verantwortlich.

1972 produziert Wega auch in der früheren Akkord-Kofferradiofabrik in Herxheim.

1975 kauft eine Tochtergesellschaft der Sony Corp. in Tokio den Betrieb. Jetzt kommen die Innereien aus Japan, doch stoppt Wega Hörfunkgeräte schon 1979 mit dem Technik-High-End-Modell «Lab Zero». Ab 1980 heisst die Produktions-GmbH Sony-Wega .
