Richtige Fernseher haben Röhren!

In Brief: On this site you will find pictures and information about some of the electronic, electrical and electrotechnical 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 ! !

LOEWE MCS 11 (Artikel-Nr: 60481) YEAR 1980.














































































































LOEWE MCS 11 Television with 26 Inches (66cm) from LOEWE a German now dead constructor of the BEST tellye of the world.
Incorporates a stand structures which contains Speakers. Quite rare this
set.
The LOEWE MCS 11 Introduced the Monocarrier chassis first time developed by LOEWE and uses the PHILIPS 30AX SYSTEM CRT TUBE.The 30AX system, which Philips introduced in 1979, is an important landmark in the development of colour picture systems. With previous systems the assembly technician had to workthrough a large number of complicated setting-up procedures whenever he fitted a television picture tube with aset of coils for deflecting the electron beams. These procedures were necessary to ensure that the beams for the three colours would converge at thescreen for every deflection. They are no longer necessary with the 30AX system: for a given screen format any deflection unit can be combined  with any tube to form a single 'dynamically convergent' unit. A colour-television receiver can thus be assembled from its components almost as easily as a monochrome receiver. The colour picture tube of the PHILIPS 30AX system displays a noticeably sharper picture over the entire screen surface. This will be particularly noticeable when data transmissions such as Viewdata and Teletext are displayed. This has been achieved by a reduction in the size of the beam spot by about 30%. Absence of coma and the retention of the 36.5 mm neck diameter have both contributed to increased picture sharpness. Coma has been eliminated by means of corrective field shapers embedded in the deflection coils which are sectionally wound saddle types. The new deflection unit has no rear flanges. enabling uniform self-convergence to be obtained for all screen sizes. without special corrections, adjustments, or tolerance compensations. Horizontal raster distortion is reduced and no vertical correction is required. One of the inventions in 30AX is an internal magnetic correction system which obviates static convergence and colour purity errors. This enables the usual multiple unit to be dispensed with. together with the need for its adjustment !  New techniques have been employed to achieve close tolerance construction of the glass envelope. In addition, the 30AX picture tube incorporates two features whereby it can be accurately adjusted during the last stages of manufacture. One is the internal magnetic correction system. The other is an array of bosses on the cone that establish a precise reference for the axial purity positioning of the deflection unit on the tube axis and for raster orientation. During its manufacture, each deflection unit is individually adjusted for optimum convergence. The coil carrier also incorporates reference bosses that co-operate with those on the cone of the tube. ' Since every picture tube and every deflection unit is individually pre-aligned, any deflection unit automatically matches with any picture tube of the appropriate size. The deflection unit has only to be pushed onto the neck of the tube unit it seats. Once the reference bosses are engaged, the combination is accurately aligned and requires no adjustment for convergence, colour purity or raster orientation. With no multiple unit and a flangeless deflection unit, there is more space in the receiver cabinet. Higher deflection sensitivity means that less current is consumed, and consequently less heat is produced. This increases the reliability of the TV receiver again. 30AX means simple assembly. Any picture tube is compatible with any deflection unit of the appropriate size and is automatically self-aligning as well as being self-convergent.

The well-known 20AX features of HI-Bri, Soft-Flash and Quick-vision are maintained in the new 30AX systern.  In their work on the design of deflection coils in the last few years the developers have expanded  the magnetic deflectionfields into 'multipoles', This approach has improved the understanding  of the relations between coil and field and between field and deflection to such an extent that  designing deflection units is now more like playing a difficult but fascinating game of chess than  carrying out the obscure computing procedure once necessary.

 Featuring a Microprocessor-controlled television appliance with a local control and/or a wireless or wire-connected remote control , with setting elements for the individual functions, on the actuation of which digital or analog setting information data for the control and switching on and off of variable and fixed appliance functions are generated, which data are stored in a store and switched through for the setting of function setters, whith a data line and/or a control line for the special transmission of the control commands by means of addresses and data bus to the stores associated logically interlinked with the function setters, characterised by the combination of the following features : a control-part processor with several inputs, into which the input commands from the local control and/or the remote control and possibly present base value setters are given in as digital or analog values serially through one input or parallelly through several inputs, which control-part processor encodes the present input commands in a coding circuit or recodes them in suitable manner so that each command consists of a digital word with setting and address information data readable out by the function processors associated with the function setters, a non-volatile readable store, which is associated with the control part and which stores the input commands or the equivalent digital words and transmits the setting information data and the address serially in the form of digital words at the output as data bus , and with function processors which display bus decoders , data stores and digital and/or analog function setters with associated digital-to-analog converters , at the inputs of which the serially written words are present simultaneously, of which, however, only that bus decoder is activated, which is addressed by the address placed in front of the information data and which is freed through the control lines (clock, DLEN), which function processors display further inputs, through which the signals are fed in, which are to be influenced according to the setting commands and taken off from the chassis, in that a control and/or regulating circuit , which compares the preset data with data interrogatable through the control and/or regulating circuit in the appliance and which in correspondence with the deviation of the actual value from the intended value readjusts the signal to be influenced or switches the signal passage, is connected to the data store of the function processor.
It's an interesting fact that the cathode ray tube, which was amongst the very earliest thermionic devices, seems likely to be amongst the very last in everyday use. Receiving valves are largely things of the past, while timebase valves now belong in the service department. The development of the CRT continues apace however, and one cannot see any likelihood of its demise. Solid-state displays have been talked about, and demonstrated, but anything likely to compete on cost and performance grounds with the modern colour tube seems forever to be "at least ten years away". The early experiments with cathode-ray tubes were carried out in the last century. By the turn of the century, crude CRTs could be made. An early CRT, the Wehnelt hot cathode tube of 1905, is on display at the IBA's Television Gallery. By 1910, Alexander Campbell -Swinton had come to appreciate the possibilities of the CRT as a pick-up and display device for television, and put forward suggestions for such a TV system. It was a while however before the type of tube we know today appeared. The tubes of the 1910-30 era were gas focused devices (relying on residual gas to focus the beam), the vacuum pumps of the period producing only a poor vacuum. By the time of the start of the BBC's TV service in 1936 however the modern type of tube had arrived. It was a triode device with external focusing and a deflection angle of around 50°. The usual sizes were 9 and 12in., and the e.h.t. was about 5kV. Post-war developments during the 1950s saw some important innovations. The deflection angle went to 70°, then 90°, then 110°; multi -electrode gun assemblies with electrostatic focusing were introduced; the e.h.t rose to 20kV; improved phosphors became available; and the advent of the aluminised screen considerably improved the brightness and contrast (by reflecting all the phosphor light emission forwards) while overcoming the problem of ion bombardment. Meanwhile, colour had come. The principle of the shadowmask tube had been suggested in the 1930s, but development (by RCA) had to wait until proposals for an acceptable, practical colour broadcasting system were put forward. A regular colour service was started in the USA in 1954, and the receivers were fitted with 21in. shadowmask tubes. Early developments included the use of improved phosphors, but essentially the same tube confronted us with the advent of colour transmissions in Europe in 1967. As you all know, it had three guns mounted in a triangular formation, a dot-phosphor screen, a massive convergence system in two sections (radial and lateral), plus purity magnets and a large metal shield on which the degaussing coils hung. It also needed both NS and EW raster correction circuitry. The first versions in Europe had a deflection angle of 90° : when the 110° version came along in the early 1970s the convergence and raster correction circuitry required were even more complex, but the degaussing shield had disappeared inside the tube. At much the same time however the first major breakthrough in large screen tube design occurred (we put it that way because the innovating Sony Trinitron was at the time mainly a small screen tube) - the RCA PIL tube with its in -line guns, phosphor -striped screen, and slotted shadowmask. The design of the yoke to provide self -convergence in conjunction with the in -line gun arrangement meant that no dynamic convergence system was required, while some simple manufacturer preset magnets provided static convergence and purity correction. Sets using this tube first appeared in Europe in 1975, and meanwhile the PHILIPS 20AX system had come along. Over the last few years the pace of development has quickened to a striking extent. We've had quick warm-up cathodes, the hi-bri technology which increases the shadow mask's transparency, the contoured line screen, the super -arch mask, pigmented phosphors, soft flash to reduce flashover damage, redesigned focus arrangements, and increased use of an earlier development, the black -stripe screen. The latest generation of tubes require no NS raster correction circuitry, which is all part of a parallel development in yoke technology, while the need for EW correction is also in the process of being designed out. With the new Philips 30AX tube, the static convergence and purity system disappear inside the tube in the form of a small internal magnetic ring. It's all a long way from Wehnelt's hot -cathode tube of 1905. The latest colour tubes are compact and have all the various correction arrangements required built in. They are amazing feats of precision engineering, and a solid-state alternative seems as far away as ever. Is there any farther to go along this path? Well, single -gun colour tubes using the beam indexing principle are now understood to be a practical proposition for small screen tubes, so we can't be too sure.

The Loewe brand values have been shaped consistently over a long period of time. It all began in Berlin in 1923, with the brothers Dr. Siegmund and David Ludwig Loewe. Since then, one principle has always been adhered to: setting new standards with innovation for the senses.

Loewe established an impressive level of quality as early as 1931, with the first public television transmission worldwide. Loewe has been producing quality made in Germany at its location in Kronach since 1948. In the last 20 years, in addition to the Art 1 from 1985 becoming a design classic, Loewe has received numerous national and international awards.

In 2005, Loewe became the leading premium flat screen television provider. It made its breakthrough with the Loewe Individual: the first flat screen television with individualised housing versions, set-up options and inset colours. In 2008, with the Loewe Connect, Loewe heralded a new, digital television age where non-system end devices could be connected to a flat screen television set. One year later, Loewe combined uncompromising ultraslim design with leading state-of-the-art technology in the Reference range. In 2010, Loewe ultimately introduced the Mediacenter, which provides perfect entertainment networking throughout the home. Another step towards the future.

Loewe AG (pronounced [ˈløːvə]) is the parent company of the German Loewe group. The Loewe group develops, manufactures and sells a wide variety of electronic, electrical and mechanical products and systems, and specialises in the field of consumer and communication technology. The company was founded in Berlin in 1923 by brothers Siegmund and David L. Loewe. The company has its headquarters and sole production facilities in Kronach, Franconia. Today, the range has expanded to include televisions, Blu-ray players, DVD recorders, hard disk recorders, multiroom systems, speakers and racks. The trend is shifting from individual products to complete home entertainment systems. Loewe AG is also represented internationally by sales partners and subsidiaries. These include subsidiaries in the Benelux countries, France, Italy, Austria and the UK. There are exclusive Loewe Galeries acting as flagship stores in many cities around the world, including Madrid, London, Paris, Amsterdam, Rome, Copenhagen, Vienna, Moscow and Hong Kong.


LOEWE Company history
It all began in 1923 in Berlin, when Dr Siegmund Loewe and his brother David Ludwig Loewe established a radio manufacturing company called Radiofrequenz GmbH. Their work with the young physicist Manfred von Ardenne in 1926 led to the development of the triple tube, which was first used in the Loewe OE333 radio receiver. This tube prompted Loewe’s multi-tube production and is today lauded as the world’s first integrated circuit.

Television development began at Loewe in 1929. The company worked together with British television pioneer John Logie Baird. In 1931, Manfred von Ardenne presented the world’s first fully electronic television to the public on the Loewe stand at the 8th Berlin Radio Show.

When Hitler came to power in Germany, Siegmund Loewe had to emigrate to the USA in 1938, where he developed friendship with yet another forced emigrant, Albert Einstein.

In 1949, Siegmund Loewe regained possession of company property and took over as chairman of the supervisory board. In the 1950s, Loewe began producing the Optaphon, the first cassette tape recorder, and manufacturing televisions in Kronach. 1961 saw the first European video recorder, the Optacord 500, enter mass production.

In 1962, the family company tradition ended with the death of Siegmund Loewe. Subsidiaries of the Philips group took over the majority of shares. Under this management, which continued until 1985, the company increasingly specialised in the development and production of televisions.

In 1963, the first portable television, Loewe Optaport, was launched. It had a 25cm screen and built-in FM radio. The first Loewe colour televisions were launched along with the introduction of colour television in Germany. Loewe revolutionised television production in 1979 with a fully integrated chassis (everything on a single board). The first European stereo television followed in 1981.

In 1985, management made Loewe a privately owned company again after Philips sold its shares. In the same year, Loewe created the Art 1, a new generation of TVs with a focus on design.

The CS1 represented another international first in 1995 as the world’s first fully recyclable television. At this time, the course was also set for systematic further development as a multimedia specialist.

1998 marked two more milestones in the company history: the launch of the Xelos @ media, the first television with internet access, and that of the Spheros, the first Loewe flat-screen television. In the following year, Loewe AG became a publicly listed company.

With the Individual, the first flat-screen TV with individual housing options, set-up solutions and inset colours, Loewe took a decisive step and became a premium flat-screen TV manufacturer.

Loewe Connect, the world's first smart TV with fully integrated network capability for wireless access to picture, music and video files on a computer or external hard drive followed in 2008.

LED technology was adopted at Loewe in 2010 in the new Individual. In the following year, Loewe introduced 3D picture display to its Individual range.

1926: Aktiengesellschaft D.S. Loewe, Berlin-Steglitz;
1930: Radio-Aktien-Gesellschaft Dr. S. Loewe;
1933 (nach): Löwe-Radio AG;
1942: Opta-Radio AG;

1965: Loewe Opta GmbH, Kronach.
Radios: 1923 bis 1926, Loewe 1927 bis 1978. TV-Fabrikation danach.


Nach Studium der Physik und Elektrotechnik promoviert Siegmund Loewe (Berlin 6.11.1885-28.5.1962 USA) unter Max Wien mit magna cum laude zum Dr. phil. Er tritt bei der Firma Telefunken ein und wechselt 1915 zur Firma Huth, wo er die Leitung der Laboratorien und der Patentabteilung übernimmt. 1918 mietet Loewe in Berlin SW61 eine 7-Zimmer-Wohnung und erstellt mit einer kleinen Entwicklungsgruppe einen Telefonie-Röhrensender, dessen Sendungen in dem nicht weit entfernten Haus des Scherl-Verlages von Otto Kappelmayer zu empfangen sind. Um seine Kenntnisse zu erweitern, begibt sich Loewe in die USA. Einen ausführlichen Bericht von und über Loewe finden Sie in [1-99], woraus Sie erkennen können, dass Loewe das treibende Element für den Rundfunk in Deutschland war. Wie er gegen den Monopolanspruch von Telefunken/Lorenz/Huth (Funkkartell «Rundfunk GmbH») kämpfte und weitere Details finden Sie in [6-121].

Nach seiner Rückkehr aus den USA wird das Versuchslabor von Loewe zum Kristallisationspunkt der jungen Funktechnik. Im Dezember 1921 erhält Loewe Besuch von Lee de Forest, und sie verbessern gemeinsam Röhren. 1921 entstehen auch zwei grundlegende Patente für den Konus-Lautsprecher. Loewe eröffnet ein zweites Laboratorium und gründet 1923 die Loewe-Audion-GmbH für die Herstellung von Radioröhren sowie die Radiosender GmbH.

Im Dezember 1921 lernt der Realschüler Manfred von Ardenne den Radiopionier Loewe in einem Elektrikergeschäft kennen und ist darauf häufiger Gast in den Laboratorien von Loewe. Ein Autor schreibt, dass Loewe zum «Ziehvater» des jungen von Ardenne wird und er in der Familie aufgenommen ist, doch von Ardenne beschreibt dies in seinem Buch «Eine glückliche Jugend im Zeichen der Technik» (DDR) nicht.

Die wahrscheinlich 1923 gegründete Loewe Radio GmbH führt der jüngste Loewe-Bruder Bernhard. Das D bei D.S. Loewe steht für den älteren Bruder, David (Teilhaber).

Radiofrequenz GmbH und Loewe-Audion GmbH (1923-27):
Am 22.1.23 erwirbt Dr. Siegmund Loewe die seit 1918/19 bestehende Mechanische Werkstatt Grüttner & Lütgert in Berlin-Friedenau und gründet die Radiofrequenz GmbH. Die ersten Geräte sind für den Export bestimmt. Davon sind mir die Typen EA51, EA52 und EA54 bekannt. EA steht für «Empfangs-Apparat».

Im Jahr darauf stellt der Betrieb die Ziffer 9 vor die laufende Nummer. Der Sprung von EA958 auf EA980 deutet auf andere Artikel hin (z.B. Trichterlautsprecher und kombinierte Geräte etc.). Nachher ist keine Nummernsystematik mehr zu erkennen, ausser den Buchstabenkombinationen wie OE (Orts-Empfänger), FE (Fern-Empfänger), KV (KW-Vorsetzer), RO (Rückkopplungs-Ortsempfänger) etc.
1927 gibt Loewe den Namen Radiofrequenz auf und verwendet seinen eigenen Namen. Die drei Geräte OE333, 2H3N und NVG gibt es unter beiden Namen, da sie Loewe 1927/28 ohne neue Modelle weiter produziert. Mehr als eine Million dieser Geräte lassen sich zum Stückpreis von 39.50 RM verkaufen, und die Tagesproduktion erreicht zeitweise 2000 Einheiten.

Im Oktober 1923 gründet Loewe eine weitere Gesellschaft zur Herstellung von Rundfunkröhren mit dem Namen Loewe-Audion GmbH, ebenfalls an der Niedstrasse 5 in Berlin-Friedenau gelegen. Zuerst entstehen dort Wolfram-, dann Thoriumröhren als «Sparröhren». Im September 1924 meldet Loewe die grundlegenden Patente zur Dreifachröhre mit integrierten Bauteilen an, die 1926 als 3NF mit dem «Loewe Ortsempfänger OE333» einen legendären Ruf erreicht.

Loewe, Löwe, Opta, Loewe-Opta
Die Schrift «Loewe-Story» aus dem Hause Loewe-Opta zeigt die Abbildung eines «Detektor-Empfängers» mit zwei Steckspulen, der angeblich zur Eröffnung des Rundfunks bereitstand. Es ist aber ein umfunktionierter Sperrkreis für den Empfänger 2H3N, Baujahr 1927, was auch aus dem Firmenschild mit «Berlin-Steglitz» hervorgeht.

1926 entsteht die Aktiengesellschaft D.S. Loewe, Berlin-Steglitz. Als zweites Gerät unter der neuen Marke Loewe bzw. Loewe Radio gilt der auf der Funkausstellung im September 1926 gezeigte Fernempfänger 2H3N zu RM 150. Auch Lautsprecherboxen mit Loewe-Konus-Lautsprecher und Stoffbezug im «Südsee-look» sind nun erhältlich. Wegen der steigenden Anzahl Rundfunksender treten Trennschärfeprobleme auf, so dass die Dreifachröhre für den Einbezug einer Rückkopplung einen siebten Anschluss erhält. Diese «3NF7» baut Loewe ab 1928 in alle OE333, 2H3N und in das dritte Gerät, den RO433 ein. Die elektrische Schallplatten-Abtastdose LR150 erregt Aufsehen; Gewicht 260 g! Die Dose verlangt einen Abspielwinkel von 55 Grad. Die 3NF gibt es nun auch mit Oxydkathode als 3NFB mit einem Verbrauch von 0,13 statt 0,34 A Heizstrom - zudem beträgt die Verstärkung etwa das Doppelte. Weitere Details zu Firmengründungen von Loewe siehe [638967]. Es sind dies z.B. die Eudarit-Pressgut GmbH für Bakelitgehäuse etc. und die Ortophon-Apparatebau GmbH für den Lautsprecherbau.

1929 bringen die Loewe-Firmen den «Vollnetzanschluss-Empfänger R533» heraus, der mit einer nochmals verbesserten Dreifachröhre, der 3NFW mit indirekter Heizung, ausgestattet ist. 1929 entsteht Loewe's Berliner-Radio-Handels-Aktiengesellschaft. Die Baird Television Company Ltd., London, bietet Loewe die Auswertung und Entwicklung ihrer Schutzrechte und Entwicklungsarbeiten auf dem Fernsehgebiet in Deutschland an. Da dieses Angebot die finanziellen Möglichkeiten von Loewe übersteigt, regt Dr. Loewe eine Beteiligung von Zeiss Ikon, Dresden, und Robert Bosch, Stuttgart, an. Es kommt Mitte 1929 zur Gründung der Fernseh-AG in Berlin, die 1939 im Firmenverband Robert Bosch aufgeht.

1930 fasst Loewe verschiedene seiner Firmen unter dem Namen Radio-Aktien-Gesellschaft Dr. S. Loewe zusammen und mit dem EB100W (1931 EB100G) beginnt die Reihe der Empfänger mit integriertem Lautsprecher.

Im Auftrag der Loewe-Firmen bringt von Ardenne aus seinem eigenen Labor 1930 erste brauchbare Vorschläge zur Helligkeitssteuerung, um auf einem Bildschirm ein gut modulierbares Bildraster zu schreiben. Meine gasgefüllte Braun'sche Röhre aus dem Labor von Ardenne zeugt für die Forschung um 1926.

Auch auf der Senderseite entwickelt Loewe elektronische Medien auf der Grundlage des «Flying-spot-Abtasters», um Filme elektronisch übertragen zu können. Am 25.4.31 veranstalten Dr. S. Loewe und M. von Ardenne in den Lichterfelder-Laboratorien eine Vorführung vor der Fachpresse. Bald darauf kann Loewe die Qualität der mechanischen Systeme erreichen und übertreffen. Siehe [1-127f]. 1932 geht von Ardenne eigene Wege. 1933, ein Jahr vor den Mitbewerbern, erkennt Dr. Loewe die Notwendigkeit von Allstrom-Apparaten und bringt den 1-Kreis-Empfänger «Edda» auf den Markt. (Ganz so richtig ist das nicht: zumindest Emud kommt 1931 mit «Allstrom», EE). Zu der Zeit halten sich Wohnungen mit Gleich- bzw. Wechselstrom etwa die Waage und eine Familie, die umzieht, kann den transformatorlosen Apparat weiterverwenden. Der Apparat führt die Allstrom-Dreifachröhre WD33. Das Allstromkonzept führt Loewe auch für Mehrkreis- und Superhet-Empfänger mit den Röhren WG34, WG35 und WG36 fort.

Auf dem in England bestellten Sattelschlepper mit einer Fernseh-Sendereinrichtung steht anlässlich der Premiere vom Juli 1934 in London gross der Namenszug Radio A.G. D.S. Loewe. Das Regime in Deutschland lässt die Firma jedoch bald in Löwe-Radio AG umtaufen und 1942 in Opta-Radio AG. Loewe wandert 1936 in die USA aus und gründet dort die Loewe Radio Inc. Er hat 1938 aus dem Vorstand in Deutschland auszuscheiden.

1941-44 fertigen die Opta-Betriebe ausschliesslich Rüstungsgüter; Opta-Radios sind dann Fremdtypen [638966-19]. Man gliedert Grassman in den Opta-Betrieb ein. Es entstehen Auslagerungsbetriebe, z.B. in Oberlungwitz in Sachsen. In Berlin-Weissensee entsteht während des Krieges ein Betrieb für Röhrenbau [DRM94].

Noch im März 1945 verlagert das Unternehmen eine wichtige Kriegsfertigung nach Küps bei Kronach. Dies ist die Keimzelle der neuen Firma, denn 1948 kann S. Loewe seine Wiedergutmachungsansprüche durchsetzen und erhält das Sagen beim demontierten Hauptwerk in Berlin und der Auslagerungsstätte in Küps bei Kronach. In Küps fabriziert Loewe ab 1946. Gemäss «Loewe-Story» gibt es vor November 1947 den «Kronach», wahrscheinlich 547W, in einer Auflage von zwei Geräten pro Tag. Ein getrenntes Werk in Düsseldorf-Heerdt offeriert als Firma Opta-Spezial GmbH von 1950 bis 1954 Opta-Spezial-Radios [6-124]. Konsul Bruno Pieper wirkt als Generaldirektor.

Jedenfalls: Auf der Leipziger Messe von 1947 sind wieder Loewe-Entwicklungen zu sehen. Die Firma erzeugt 1950 mit dem «Optaphon» das erste deutsche Kassetten-Tonbandgerät. 1961 ist Loewe mit dem «Optacord 500», einer für den privaten Gebrauch konzipierten Video-Anlage, führend beim Bildschirmtext und baut vor allem modernste TV-Empfänger - ein Steckenpferd von Dr. S. Loewe. Er stirbt 1962.

Bis 1978 fertigt die Firma Radios in Berlin, löst diesen Betrieb aber auf. Der Mitarbeiterbestand bei Loewe beträgt Ende der 80er Jahre ca. 1500. Die Loewe Opta GmbH, Kronach, gehört in den 90er Jahren zu 51,9 % der Management GBR (Gesellschaft leitender Mitarbeiter der GmbH) und zu 48,1 % zu Matsushita (Panasonic), wobei eine gute gegenseitige Befruchtung für das Hauptprodukt, TV, zum Tragen kommt.

Loewe in Ostdeutschland:
Opta Leipzig, ab 1950 VEB Stern-Radio Leipzig genannt, geht 1952 im VEB Fernmeldewerk Leipzig auf. Die Radioproduktion endet 1950/51.

Nach dem Krieg versuchen Loewe-Mitarbeiter des Zweigwerkes in Oberlungwitz in Sachsen, Maschinen und Vorrichtungen nach West-Berlin zu transportieren, doch die Sowjets verlangen, dass diese Güter in die Röhrenfabrik Berlin-Weissensee gelangen.

Dieser Loewe-Betrieb arbeitet mit der Röhrenfabrik in Berlin.

Loewe hat auch in anderen Ländern Produktionsstätten, so z.B. in Grossbritannien. Vor allem aber auch Handelsniederlassungen, wie Loewe Radio S.A., 3 quai de Willebroeck, Bruxelles (adress in 1932).

  2. Hi, Morgan,

    Throwing away the "LOEWE MCS 11" is NOT good.

    That series / type is quite rare and pretty unique for design, technology, features.

    Considering it only a marketing value has nothing to do with his "real Value".

    LOEWE is LOEWE............. forever !

    FRANK.

The most important thing to remember about the Comment Rules is this:
The determination of whether any comment is in compliance is at the sole discretion of this blog’s owner.

Comments on this blog may be blocked or deleted at any time.
Fair people are getting fair reply. Spam and useless crap and filthy comments / scrapers / observations goes all directly to My Private HELL without even appearing in public !!!

The fact that a comment is permitted in no way constitutes an endorsement of any view expressed, fact alleged, or link provided in that comment by the administrator of this site.
This means that there may be a delay between the submission and the eventual appearance of your comment.

Requiring blog comments to obey well-defined rules does not infringe on the free speech of commenters.

Resisting the tide of post-modernity may be difficult, but I will attempt it anyway.

Your choice.........Live or DIE.
That indeed is where your liberty lies.
