Okay, that's for the small Fairchild broadcast lathes. Not studio grade
gear, but a lot better than the Presto junk that most stations bought. There
is some documentation on them around here somewhere and I am pretty sure I
have schematics.

That's very exciting. I would be more than willing to compensate you for
finding and copying them. I bought it from a HiFi dealer who routinely rebuilds
old tube amps and resells them. I traded him a Dyna Stereo 70 w/o tubes for it,
because I was really excited to hear the mic preamp in it.
He had already recapped and retubed the poweramp section, and modified the
pickup input to accept unbalanced line level. As I mentioned in an earlier
post, it sounds rich and clean (not muddy) when I plug a passive P-bass into
it.
My original interest was the balanced mic preamp. However, it sounds really
thin. I wonder if those caps need replacement or if that was intentional given
the otiginal purpose.

Look and see if you can get the turntable and cutter that came with that.
The turntable was probably the first electronically-controlled table around.
No servo, but it had a synchronous motor driven by a pair of 6L6 tubes for
very precise speed control. BRBR

I have owned this Fairchild thing for 8-10 years. Got it around the same time I
started listening to V72a's and Altec 1567's as "color" pres - hoping for a
cheap Irishman's delight - great sound/small cash outlay.
I asked the guy I bought it from where the rest of the rig went and he had no
idea.
