What is this thing?

Wow! Thanks for that link, Herki! Such great history. I glanced at it and will go through it in depth when time permits. I already knew quite a bit about the early Ampex history. I would like to know more about the development of the Magnetophon at AEG. I know it was shown at the World's Fair in 1939. I believe that was still a DC bias machine. I heard that it had already been converted to AC bias before War's end. I think the one Jack brought back was still DC bias and was converted. Anyone know if that is correct?

Best,

Kev

Kev, the link "http://www.pavekmuseum.org/jmullin.html" states that:

"The advanced AC bias tape recorder was widely used in wartime German broadcasting. Mullin said, "The Magnetophon had been used at Radio Frankfurt and at other stations in occupied Germany by the time I stumbled onto it, but there was no official word that such a thing existed. The people who were using it to prepare radio programs apparently were unaware of its significance. For me, it was the answer to my question about where all that beautiful night-music had come from.”1 Later, Mullin would joke that, “The reason we didn't know about the Magnetophon was that the Germans never bothered to classify it as top-secret.” ...herki[quote/]
