Slimming down my analog studio storage and lots of stuff will be offered here and there.  I am offering a V397b playback amplifier card manufactured in the turn 60's and 70's  by Telefunken for their famous and great sounding Telefunken M10A, M5c and M15 studio tape recorders. You are buying a single unit of 2. This is fully discrete, transistored design with transformer. Sounding pretty good, better than any other transistor units here in Europe (American transistor amplifiers were sounding awesome too).  Coming in original, very good cosmetical and possibly technical condition.  I mean they were all working when machine was dimantled for parts. No further warranty as they are 60 years old now. You may need them for spare, replacement or just building your own set for any tape machine.  No option to build this quality amplifier for these money today.  Feel free to ask questions.
