TUBE MUSEUM NEW YORK
THE HISTORY of AEG-TELEFUNKEN
Around the start 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 Kaiserliche Marine; the other one, under Karl Ferdinand Braun, at Siemens, for the German Army. Their main competitor was the British Marconi Company.
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, adding extensively to the German air defence against British-American Aerial Bombing. During the war, manufacturing plants were shifted to and developed in west of 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.
In 1967, Telefunken was merged with AEG , which was then renamed to AEG-Telefunken.
Production plants were located in:

..."Dear tubemuseumusa,
I just want to thank you again for helping me get another matched tube after only ordering one by accident. They are by far my favorite 6AK5 tube I've tried to date! Much livelier than the (Mullard) M8161 tubes I was using, i.e. waaaay better mids and bass! I'm listening to some Ween on them right now as a matter of fact.
Thanks, Mark - mab1376"...

R-390A Military Shortwave Radio Receiver
The R-390A was deployed to most branches of the US military and remained in general use through the 1980s. The last major update to its documentation was in 1984. As the military procured newer receivers, many R-390As were released to surplus while others were destroyed. Some receivers were retained by the services, however, when they found that the R-390A's vacuum tube circuitry could easily survive an electromagnetic pulse. There are reports, possibly apocryphal, that R-390A receivers are still in use aboard U.S. Navy submarines since the receiver can withstand the strong radio frequency fields found aboard ship.
Many of the R-390As that exist today are in the hands of vintage amateur radio collectors and amateur radio operators who contend that few modern solid state communications receivers can equal its performance. There is a wealth of information, both printed and electronic, devoted to R-390A restoration and maintenance, as the R-390A is widely considered an example of the best of vacuum tube technology.
These tubes are an important integral tube in the overall sound, reliability and performance of your 6AK5 amp.

..." * Rp or plate resistance is the second most important parameter as it directly affects the output impedance of the preamp. Circuit designers are looking at Mu primarily, Rp next and we hardly care about Gm at all. Why then do most vendors measure Gm and Gm alone? Because most testers only measure Gm! No commercial tester ever measured Mu either (until the AMPLITREX AT1000 was introduced.) And even the Hickock, treasured for measuring Gm, doesn’t measure it meaningfully (due to current dependency), accurately (due to calibration difficulties) or consistently (due to internal circuit drift).'"...
