TELEFUNKEN TTV32-17 YEAR 1959.

The TELEFUNKEN TTV32-17 was first Telefunken 17 inches Screen B/W television using a 110° degree CRT TUBE and was anyway a sligltly rounded screen type.

VHF channel drum selector is present and an UHF Tuner was added after time.

Tuning is obtained with rotatable drum selectors for VHF and variable rotatable capacitor for UHF.
A rotatable drum containing twelve pre-defined channel-specific filters determines the received channel, where the inductors of the input matching, the channel filter and the LO tank circuit are changed. The tuner is divided into two chambers for maximum isolation between the sensitive RF input and the mixer-oscillator-IF section with its much larger signals. Also on the drum there are eventually two separate sub-modules.
It's completely based on tubes technology.
With this concept, which essentially turned the tuner module into a kind of Lego building block construction, many different tuners became possible. Depending upon the country of destination and its associated standard and IF settings, the required filter modules would be selected. Service workshops and tv fabricants could later even add or exchange modules when new channels were introduced, since every inductor module had its individual factory code and could be ordered separately. As a consequence more versions of the tuner were produced, covering at least standards B, B-for-Italy, C. E, F and M.


The principle of the drum tuner. On an axis two times 12 regularly spaced channel-specific filter modules are mounted. In front are twelve channel filter modules for both the channel filter and LO tank circuit tuning. Seven contacts are available, and one module is shown removed. The second row contains 12 modules with five contacts for the input filter circuit. In the tuner module the front section (for mixer-ocillator and channel filter) is separated by a metal shield from the rear RF input and pre-amp section. [Philips Service "Documentatie voor de kanalenkiezers met spoelenwals", 1954]

Examples of the filter modules as used in the drum tuner. Left the 5-contact input filter, right the 7-contact BPF and LO tank filters. In both modules the coils are co-axial for (maximum) mutual coupling.





The second new valve introduced in the tuners family was the PCF80, a triode-pentode combo valve specifically designed for the VHF mixer-oscillator role. First order the circuit principles didn't change too much from the previous ECC81 based generation, with the triode acting as a Colpitts oscillator with a tuned feedback from anode to grid. The oscillator voltage was minimally 5V at the grid, and would be inductively coupled to the input of the mixer pentode. This inductive coupling was achieved by putting the oscillator coil S7 and the BPF coils S5 and S6 on the same rod inside the drum tuner filter modules, see Fig.5 above. By adjusting the distance between these coils for each channel filter module, the coupling constant could be kept more or less constant across all channels, providing as much as possible a frequency-independent mixer performance. For the mixer the pentode replaced the previous triode, providing more feedback isolation between anode and grid. All in all the new tuner must have given a considerable performance improvement compared to the previous generation.

Television receivers currently being manufactured for consumer use were capable of operation in either the VHF (very high frequency) or UHF (ultra high frequency) bands of frequencies. In order to provide this capability, however, it is necessary to include two separate tuners or tuning circuits in the television receiver with one of these circuits being utilized for VHF reception and the other being used for UHF reception. The VHF tuner conventionally is a turret type of tuner having 13 detented positions which accomplish the coarse tuning or channel selection of the VHF tuner and a separate control is provided to effect the fine tuning at each of the channel positions. Generally, mechanical channel selecting devices for VHF television tuners fall into two groups, namely, the rotary-switching type or the turret types. Turret type tuners include an incrementally rotatable channel selector shaft for selectively connecting certain ones of a plurality of tuned circuit elements to each of a plurality of channel selector positions. UHF tuners generally employ a separate control mechanism or a tuning knob and use a dial indicator of a type commonly found in manual radio receivers. UHF tuners for television receivers are usually of a continuous tuning type similar to the tuning system adapted for radio sets. Therefore, the tuning in UHF channels has been extremely difficult as compared to the tuning in VHF channels. Such continuous tuning systems for the UHF tuners has heretofore been sufficient, since only two or three UHF channels have been authorized in one locality. However, where more UHF channels, namely seven or eight channels, are available for reception, a non-continuous type UHF tuner, which enables simpler tuning operation, is desired. Nevertheless, this continuous tuning system has heretofore been satisfactory, because there were only 2 or 3 UHF band channels or stations available for reception in an area. However, where there are an increased number (7 or 8 or more, for instance) of UHF band channels or stations available for reception, a non-continuous or intermittent tuning system as is adopted for the VHF tuner is preferable.

More desirably, the fine tuning control is presettable, so that the desired channel may be readily selected by merely turning the main channel switch-over shaft. The use of two separate tuning control mechanisms in order to effect the VHF and UHF tuning of the receiver is  at best; and when a receiver is provided with remote control capabilities, generally only the VHF band of frequencies may be remote controlled and the UHF channels still must be selected manually at the receiving set location.Conventional turret tuners still leave room for improvement, especially as far as minimizing the tuner size and dimension, and simplifying the assembly, as well as lowering the manufacture costs and improving the tuner performance are concerned.


Even with 17 Inches it's big and heavy.

Completely based on tubes technology.

The tellye here in collection is fabricated in Italy by TELEFUNKEN RADIO TELEVISIONE MILANO in Italy which was at the time the Italian TELEFUNKEN factory.

This factory was even well known for his radio production in ancient times.

TV set kindly donated to me by Marshall Elia Z.

The B/W Tubes Television set was powered with a External Voltage stabiliser unit for Television (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. Conventional AC-operated television receivers exhibit several undesirable performance attributes. For example, under low-line voltage conditions such as those encountered during peak load periods or temporary power brown-outs imposed during times of power shortage, picture shrinkage and defocusing are encountered and under extreme brown-out conditions the receiver loses synchronization with a resultant total loss of picture intelligibility.

On the other hand, abnormally high-line voltage conditions are sometimes encountered, and this can lead to excessive high voltage and X-ray generation. In addition, either abnormally high steady state line voltage conditions or high voltage transients such as those encountered during electrical storms or during power line switching operations may subject the active devices and other components of the receiver to over-voltage stresses which can lead to excessive component failure.

It is a principal object of the present invention to provide a new and improved AC-operated television receiver having greatly improved performance characteristics in the presence of fluctuating power supply voltages.

A more specific object of the invention is to provide an AC-operated television receiver affording substantially undegraded performance under even extremely low-line voltage conditions without excessive high voltage and X-ray generation under even extremely high-line voltage conditions.

Still another and extremely important object of the invention is to provide a new and improved AC-operated television receiver having greatly improved reliability against component failure. 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 the
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
introduced 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.

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.
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 energized 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 a nd 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 included 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.

In brief:
Telefunken (WAS) is a German radio and television apparatus company, founded in 1903, in Berlin, as a joint venture of two large companies, Siemens & Halske (S & H) and the Allgemeine Elektricitäts-Gesellschaft (General Electricity Company).

The name "Telefunken" appears in:

* the product brand name "Telefunken";
* AEG subsidiary as Telefunken GmbH in 1955;
* AEG subsidiary as Telefunken AG in 1963;
* company merged as AEG-Telefunken (1967–1985);
* the company "Telefunken USA" (2001). Now Telefunken Elektroakustik (2009)
* the company "Telefunken semiconductor GmbH & Co KG" Heilbronn Germany (2009).
* the company "Telefunken Lighting technologies S,L" (2009)

The company Telefunken USA[1] was incorporated in early 2001 to provide restoration services and build reproductions of vintage Telefunken microphones.

Around the turn of the 20th century, two groups of German researchers worked on the development of techniques for wireless communication. The one group at AEG, led by Adolf Slaby and Georg Graf von Arco, developed systems for the German navy; the other one, under Karl Ferdinand Braun, at Siemens, for the German army.

When a dispute concerning patents arose between the two companies, Kaiser Wilhelm II decided that the two companies were to be joined, creating on 27 May 1903 the company Gesellschaft für drahtlose Telegraphie System Telefunken ("The Company for Wireless Telegraphy Ltd."), and the disputed patents and techniques were invested in it. This was then renamed on 17 April 1923 as Telefunken, The Company for Wireless Telegraphy. Telefunken was the company's telegraph address. The first technical director of Telefunken was George Graf von Arco.

Starting in 1923, Telefunken built broadcast transmitters and radio sets.

In 1928, Telefunken made history by designing the V-41 amplifier for the German Radio Network. This was the very first two stage, "Hi-Fi" amplifier which began a chapter in recording history. Over time, Telefunken perfected their designs and in 1950 the V-72 amplifier was born. The TAB (a manufacturing subcontractor to Telefunken) V-72 soon became popular with other radio stations and recording facilities and would eventually come to help define the sound of most European recordings. The V-72S was the only type of amplifier found in the legendary REDD-37 console used by the Beatles at Abbey Road Studios on every recording prior to Rubber Soul. Today the V-72 is still the most sought after example of Telefunken's design and over 50 years later continues to be the benchmark by which all other tube based microphone preamplifiers are measured. In 1932, record players were added to the product line.

In 1941 Siemens transferred its Telefunken shares to AEG as part of the agreements known as the "Telefunken settlement", and AEG thus became the sole owner and continued to lead Telefunken as a subsidiary (starting in 1955 as "Telefunken GmbH" and from 1963 as "Telefunken AG").

During the Second World War Telefunken was a supplier of vacuum tubes, transmitters and radio relay systems, and developed radar facilities and directional finders, aiding extensively to the German air defense against British-American Aerial Bombing. During the war, manufacturing plants were shifted to and developed in West Germany or relocated. Thus, Telefunken, under AEG, turned into the smaller subsidiary, with the three divisions realigning and data processing technology, elements as well as broadcast, television and phono. Telefunken had substantial successes in these markets during the time of self-sufficiency and also later in the AEG company. Telefunken was also the originator of the FM radio broadcast system. Telefunken, through the subsidiary company Teldec (a joint venture with Decca Records), was for many decades one of the largest German record companies, until Teldec was sold to WEA in 1988.

In 1959, Telefunken established a modern semiconductor works in Heilbronn, where in April 1960 production began. The works was expanded several times, and in 1970 a new 6-storey building was built at the northern edge of the area. At the beginning of the 1970s it housed approximately 2,500 employees.

In 1967, Telefunken was merged with AEG, which was then renamed to AEG-Telefunken. During this era, Walter Bruch developed the PAL color television for the company, in use by most countries outside the Americas today (i.e. United Kingdom - PAL-I), and by Brazil (PAL-M) and Argentina (PAL-N) in South America.

The mainframe computer TR 4 was developed at Telefunken in Backnang, and the TR 440 model was developed at Telefunken in Konstanz. They were in use at many German university computing centres from the 1970s to around 1985. The development and manufacture of large computers was separated in 1974 to the Konstanz Computer Company (CGK). The production of mini- and process computers was integrated into the automatic control engineering division of AEG. When AEG was bought by Daimler in 1985, "Telefunken" was dropped from the company name.

In 2005, Telefunken Sender Systeme Berlin changed its name to Transradio SenderSysteme Berlin AG. The name "Transradio" dates back to 1918, when Transradio was founded as a subsidiary of Telefunken. A year later, in 1919, Transradio made history by introducing duplex transmission. Transradio has specialized in research, development and design of modern AM, VHF/FM and DRM broadcasting systems.

In August 2006, it acquired the Turkish company Profilo Telra, one of the largest European manufacturers of TV-devices, with Telefunken GmbH granting a license for the Telefunken trademark rights and producing televisions under that name. In 2000, Toni Roger Fishman acquired The Diamond Shaped Logo & The Telefunken Brand Name for use in North America. The company "Telefunken USA" [2] was incorporated in early 2001 to provide restoration services and build reproductions of vintage Telefunken microphones. In 2003, Telefunken USA won a TEC Award for Studio Microphone Technology for their exact reproduction of the original Ela M 250 / 251 Microphone system. Telefunken USA has since received several TEC Awards nominations for the following microphone systems: the Telefunken USA M12 or C12 (originally developed by AKG), the R-F-T M16 MkII, and the AK47. The Historic Telefunken Ela M251 microphone system entered the MIX foundation's Hall of fame in 2006. In 2008, Telefunken USA won a second TEC Award for its new Ela M 260 microphone.

As a result of a conference held in Frankfurt in May 2009, Telefunken USA has been renamed Telefunken Elektroakustik ("Electrical Acoustics") Division of Telefunken and awarded the exclusive rights to manufacture a wide variety of professional audio products and vacuum tubes bearing the Telefunken Trade Mark, in over 27 countries worldwide. Telefunken Elektroakustik now uses the Telefunken trademark for Professional Audio Equipment & Component Based Electronics, such as Capacitors, Transformers, Vacuum Tubes in North America, South America, Europe, Asia and Australia.

TELEFUNKEN HISTORY:

1903 – 1922
TWO ARCH RIVALS. ONE INNOVATIVE COMPANY

At the beginning of the last century, two rival research groups were working in the field of
wireless telegraphy. The Slaby-Arco group was represented by the radio-telegraphy department
of AEG, founded in 1899. The other as the Braun-Siemens group, represented by a company
called Gesellschaft für drahtlose Telegraphie, System Prof. Braun und Siemens & Halske
GmbH. Under the advice of Emporer Wilhelm II, the two groups merged to form the
Gesellschaft für drahtlose Telegraphie mbH company on May 27, 1903. And the rest is history.




A TELEFUNKEN FIRST
The very first Telefunken customers were the German Army and the Imperial Navy.
Telefunken was proud to deliver the first two transmitters for the new coastal radio station, Norddeich
Radio, in November 1905. In October 1906, the expansion of a much larger Nauen station was
completed with a range of 300 km and HF output of 10 kW. Welcome to the power of
Telefunken.


MEET DR. TELEFUNKEN

Dr. Georg Graf Von Arco was the first Technical Director and Managing Director of the
Gesellschaft für drahtlose Telegraphie mbH in 1903. He was also the holder of more than one
hundred patents. Among other inventions, he initiated the high-frequency mechanical
transmitter and the wavemeter. Necessity is the mother of invention. Or in this case, German
inventions.


1923 – 1936
TELEFUNKEN GOES COMMERCIAL

On April 17, 1904, the company changed its name to "Telefunken, Gesellschaft für drahtlose
Telegraphie", and on July 26, 1932 Telefunkenplatte GmbH officially began its commercial
activity with registered capital of 100,000 Reichsmarks.
The station in the Telefunken building, Tempelhofer Ufer 9 in Berlin, began broadcasting
concerts regularly two and a half months before the official start of the "Deutsche
Rundfunkverkehr". The world tour of the Graf Zeppelin airship in 1929 got off the ground by
using Telefunken transmitters, receivers and directional equipment exclusively.
Also, on October 31, 1928, during the 5th Grand German Radio Exhibition in Berlin, Telefunken
presented a television set with the Karolus-Telefunken system, a scanning process of film
images through a Mechau projector with a Nipkow disk, in public for the first time.


MEET TELEFUNKEN’S MAD SCIENTISTS

Dr. Hans Bredow is considered to be the "Father of Broadcasting". He was employed at
Telefunken from 1904 to 1919 as a Project Manager, and later as Managing Director.
Prof. Dr. Walter Bruch developed the very first electronic television camera, with which he
participated in the live broadcast of the Olympic Summer Games in Berlin in 1936. He also
earned international fame by inventing the PAL color television system. He joined Telefunken's
Television and Physical Research Department in 1935.
These two innovators thought out of the “TV box” and helped shape and make Telefunken what
it is today.


WELCOME TO RADIO TELEFUNKEN

The German radio station in Zeesen near Königswusterhausen (8 kW shortwave transmitter) was built by Telefunken and was officially placed in service on August 28, 1929. The Mühlacker radio station (60 kW output) was handed over on December 20, 1930. Telefunken is now in, and on, the air.


TELEFUNKEN GOES FOR THE GOLD, SILVER AND BRONZE

In 1935, Telefunken equipped the Olympic Stadium, the Maifeld and the Dietrich-Eckhardt
Stage with electrical-acoustic equipment for the Olympics. On August 1, 1936 at the XI Olympic
Summer Games in Berlin, an electronic television camera, known as the Ikonoskop, was used
for the first time for a direct transmission. Again, another Telefunken first. And second. And third
1936- 1954


NOW PLAYING ON CHANNEL TELEFUNKEN

The first fully electronic television studio equipped by Telefunken for the Deutsche Reichspost
was opened with a live broadcast in August 1938. The 500 kW long wave transmitter in
Herzberg, also known as the most powerful German broadcast transmitter, was supplied by
Telefunken and began to operate on May 19, 1939.


IT’S NOT A MERGER. IT’S A POWERHOUSE

On September 24, 1941, AEG took over the 50% of Telefunken shares owned by Siemens &
Halske AG valued at 20 million Reichsmarks. Thus, Telefunken became a 100% subsidiary of
AEG. In exchange, Siemens & Halske AG received the shares of Eisenbahn-Signalwerken,
Klangfilmgesellschaft mbH and Deutsche Betriebsgesellschaft für drahtlose Telegraphie
(DEBEG) owned by AEG. Strength in numbers, indeed.


POST WWII

The reconstruction after the World War II posed a particularly difficult challenge to Telefunken.
All production facilities and equipment were destroyed, disassembled or confiscated and many
valuable experts were scattered around the world. Rebuilding began in West Germany and
Berlin in 1945, and the production of tubes and transmitters was resumed the same year. But
growth was on the way.



THE TELEFUNKEN COME BACK

In 1953 Telefunken already comprised six plants and five sales offices in Berlin, Ulm,
Frankfurt/Main and Hanover again.The range of products consisted of long-range
communications systems, radio and television transmitters, marine radios, commercial
receivers, directional and navigation systems, radar devices, deci and UHF directional radio
connections, mobile radio systems, portable radio systems, HF heat generators, measuring
equipment, electro-acoustical systems, music centers, record players, transmitter tubes, radio
tubes, special tubes and quartz crystals. As you can see, Telefunken was relentless and has
come a long way.


PROF. DR. DR. WILHELM T. RUNGE THE FIRST

Prof. Dr. Dr. Wilhelm T. Runge (1895-1987) performed trailblazing work in radio and radar
technology and played a significant role in the development of microwave in Germany. He was
especially renowned internationally in the field of high-frequency technology. As well as for
having a few, very important titles before his name.


1955 – 1962
AS TELEFUNKEN GROWS, SO DOES ITS NET WORTH

The name of the company was changed to Telefunken GmbH on January 4, 1955. Due to the
expanded business activities of Telefunken, AEG increased the capital of the company to DM
100 million in 1958.


THE FIRST GERMAN STEREO STUDIO. BROUGHT TO YOU BY TELEFUNKEN

The Sender Freies Berlin (SFB) station ordered the first German stereo studio in 1961. The
harbor radar system, supplied by Telefunken, was officially placed for service in Hamburg
Harbor in August 1962, while the first German transistor receiver (six transistors) was produced
in a test series in 1956. Prof. Dr. Walter Bruch filed the fundamental PAL "time decoder" patent
on December 31, 1962. It was the first German stereo studio of its kind, and Telefunken sought
to it that there was nothing else quite like it.


1963-1978
WHAT’S IN A NAME?

Telefunken GmbH became Telefunken AG on July 5, 1963. On June 23, 1966, the General
Shareholder Meeting of AEG passed a resolution to integrate Telefunken AG into Allgemeine
Elektrizitäts-Gesellschaft. Based on an operating lease agreement, the business activities of
Telefunken were transferred to AEG effective January 1, 1967, and were continued under the
combined name AEG-Telefunken. In March 1968, AEG-Telefunken developed a new mediumrange
radar system (Type SER-LL), which was able to detect targets at an altitude of 24,000
meters at a distance of 280 kilometers. Telefunken expands on land, as well as in the air.


TAPE RECORDERS WORTH MILLIONS

AEG-Telefunken delivered the two-millionth tape recorder, a Magnetophon 204 TS, on August
5, 1969. The ten-millionth black-and-white television picture tube was produced in Ulm on
January 27, 1970. The numbers are astounding. As is Telefunken.AEG-Telefunken delivered the
two-millionth tape recorder, a Magnetophon 204 TS, on August 5, 1969. The ten-millionth
black-and-white television picture tube was produced in Ulm on January 27, 1970. The
numbers are astounding. As is Telefunken.


ECONOMIC SLOWDOWN

There was a worldwide economic slowdown in the wake of the oil crisis in 1974. The
competition in consumer electronics sector also became more difficult due to Japanese
suppliers. The only profitable divisions of the company at this time were telecommunications
and traffic technology. But Telefunken, as usual, was known for their resilience.


1979- 1983
THE NAME GAME CONTINUES

The name of the overall company was changed to AEG-Telefunken Aktiengesellschaft on June
21, 1979. The "Aktiengesellschaft" [stock corporation] suffix was necessary due to a new law in
the European Community. In 1979, AEG-Telefunken supplied the complete telecommunications
and high-voltage equipment for the International Congress Center (ICC) Berlin, valued at DM 50
million. In January 1983 the company received an order for simulation systems for electronic
battle simulation for training Tornado crews of the German Luftwaffe and Navy. The total value
was at DM 37 million. The net worth: priceless.


TOUGH TIMES FOR TELEFUNKEN

Court composition proceedings were opened against the assets of AEG-Telefunken AG by the
District Court in Frankfurt / Main on October 31, 1982.
The District Court Frankfurt / Main confirmed the composition of AEG-Telefunken AG in
accordance with the petition filed and closed the proceedings on September 19, 1984.
Even during this difficult financial situation, AEG-Telefunken continued its business and founded
AEG-Telefunken Nachrichtentechnik GmbH (ATN), in Backnang, Germany, together with
Bosch, Mannesmann and Allianz Versicherungs-AG in 1981, as well as Telefunken electronic
GmbH (TEG) in the field of electronic components (semiconductors) together with United
Technologies Corporation (UTC), USA in 1982.
On July 1, 1992, AEG-Telefunken and Deutsche Aerospace (Dasa) founded Telefunken
Microelektronic GmbH (TEMIC), into which Telefunken Elektronic GmbH was integrated among
others. But Telefunken was determined to prevail.


A FINAL, BUT NOT LAST, TURN

Effective March 31, 1983, the French group Thomson-Brandt S.A. took over 75 percent of the
AEG-Telefunken shares in Telefunken Fernseh und Rundfunk GmbH, Hanover, Germany,
including its German and foreign subsidiaries. The remaining 25 percent were supposed to
follow on January 31, 1984. Daimler-Benz AG entered the company in autumn of 1985 and
decided in Autumn 1995 to dissolve the legal entity and transferred the remaining assets to
EHG Electroholding GmbH. Thus, the history of the company was over. But not that of its
brands.
A historical overview is offered by the company archive of AEG-Telefunken in the "Deutsches
Technikmusem Berlin", Trebbiner Str. 9, 10963 Berlin.


1984 – 2004
INNOVATION YESTERDAY. TODAY. AND TOMORROW

Currently, the Telefunken brand and name rights lie with Telefunken Licenses GmbH,
Frankfurt/Main, Germany. This company is one hundred percent subsidiary of EHG
Elektroholding GmbH, Frankfurt/Main.
EHG, on the other hand, is the legal successor of AEG Aktiengesellschaft. The licensor is
Licentia Patent-Verwaltungs GmbH, Frankfurt/Main, Germany. A differentiation is made
between brand licensing agreements, name use agreements and combined agreements. And
third-party use always requires the written approval of the licensor.
In 2003, Telefunken can look back at one-hundred years of brand history. In the past,
Telefunken was associated with significant technical developments and enjoyed the reputation
of a successful German company.
The Telefunken brand is registered in the official trademark registries of 118 countries. It
continues to be used under a variety of licensing agreements.
These are the topics that can be found in the commemorative volume "Telefunken After 100
Years - The Legacy of a Global German Brand."
Whether discovered on this website or in book, these topics should not only focus attention on
the past, but also simultaneously highlight the beginning of a strong Telefunken brand. Simply
put, it’s not just about where we’ve been. But also where we’re going.


2004 – 2009
TELEFUNKEN TODAY

Since December 2007, the trademark-right TELEFUNKEN rests with TELEFUNKEN Holding
AG, Frankfurt. Currently, TELEFUNKEN is the owner of more than 20,000 patents and active in over 130 countries around the globe.
Today, TELEFUNKEN stands for innovation and progress in the ever-changing world of
information and communications technology and is strictly focused on consumer quality – from
design concept to execution. And because of its strong heritage and long-standing tradition,
Telefunken has a high brand-awareness and a clear positioning in the field of premium
products.

" It is ironic that in the years since the introduction of PAL, Telefunken – the company that invented PAL – disappeared from the market after they were bought in the 1980s by the French company Thomson – a former SECAM protagonist.

There is further irony in the fact that even as the majority of European and Asian TV viewers benefit on a daily basis from their PAL standard TV pictures, the worldwide transition from analog to digital TV spells the end of this color standard as well as many other TV transmission standards.

What we have known as PAL, SECAM, or NTSC is now increasingly known as simply digital RGB or Y, Cr, and Cb color component signals encoded in a DVB (Digital Video Broadcasting) signal or one of its many variants such as DVB-T, DVT-S, DVB-C, DVB-H, or similar ones like your ATSC.

In the future, all this may in turn disappear into an abstract IP (Internet Protocol) packet, which would make traditional distribution channels obsolete. For example, major areas in Germany, and all of Austria may terminate their analog transmissions, replacing them with DVB-T or DVB-S only.

We will find out whether the 55th anniversary of PAL in 2018 will generate much of a resonance, if all analog TV transmissions – whether terrestrial, satellite, or cable – have been brought to an end. "
