I just received these units from an Ebay purchase. Unfortunately the 690A preamp/tuner was damaged in transit (the left front top corner was pushed in 1" which broke the glass, snapped the tuner pot and misaligned the tuner pully system). I am going to keep it anyway as I figure that I can repair all except the glass fairly easily. The faceplate was not attached, so this will just involve straightening the chassis/pully's and repairing the pot's shaft.I have searched the forums and online and cannot come up with schematics for either of these pieces, any ideas? The 690A looks to be slightly different from the FA690 in that, off the bat, it has as couple of additional slide switches on the front panel. I have never seen the inside of a FA690, so do not know how different these models really are.
The 232 looks to be the same as the SA232 if my memory serves me correctly (going back some 30 years here). Both of these units are from a console (no tube cage and top cover).
I am not very knowledgable @ this point, but plan on restoring both of the units as a learning project. I can solder and will be teaching myself to read schematics. I won't be doing anything (other than cosmetics and cleaning) until I pick up a Variac as well as the schematics. I do have a set of schematics for the Pilot 240 (thanks Les:-) and will compare the 232 to the 240 in the meantime. Perhaps they use similar circuits?
