I recently picked up a Technics quad (It is in another post) But i got this also, A JVC CD-4 demodulator 4DD-10. I have never used one but thought it might be good to have with the Technics. Any info on this would be great. ThanksView attachment 32046View attachment 32047View attachment 32048
Like yourself I have a JVC 4DD-10 CD-4 demodulator and I am also trying to locate documentation relating to it. Apart from your post and a German web page http://www.hifimuseum.de/cd-4-quadrophonie.html (see Chronology section) I have found no other mention of the 4DD-10. According to the Chronology the 4DD-10 was released around March 1972 and the 4DD-5 around June 1972.

I imagine a demodulator sold under the name "Victor" was flying under the RCA flag. RCA was the American counterpart to JVC. RCA picked up the "Victor" name when they bought out Victrola. RCA made all kinds of electronic things. I spent a good part of my career maintaining an RCA television transmitter.
