Siemens - PMUV universal mic amplifiers:
These have nice Haufe input and output transformers. I have a full set of documentation. I set one up but there are remote control gain settings that I haven't figured out and I'm not going to. Basically there is normal operation for a moment then the gain slowly ramps down to zero. I figure I 'll sell them as transformers and provide a pdf of the manuals. I recall them being +/- 15. I have 10. $65 each
RCA BN 16B:
Yeah, ain't that pretty? And it stays nice when you look inside.
and even upside down
Germanium transistors, Input transformers, Daven attenuators. It wants a fussy twistlock plug that I haven't got. I haven't tested it but apart from some slippy paint, probably from leakage from a battery, it looks top. I figure the transformers and attenuators should be worth about $250.
MCI Mic Preamps:
The underside says Mike Preamp PC2700B, Beyer input transformer and MCI 2001 opamp visible. Don't know the need voltage or anything else. I have 4. $25
each
Transformers, transformers. Transformers!
UTC A11 with A33 20db shields - $250 for the pair

These are from the output of the electronics from an RT 21 reel to reel. I don't have the schemos for either the transformer or the tape deck
