RCA BA34C Schems and pinout?
Posted: Fri Feb 10, 2012 10:55 amI grabbed this off Richard (Hybrid88) from the FS section last week. It's a germanium monitor amp, I think around the mid 60's. It seems to be in pretty reasonable condition, needs an obvious cap job, but it uses 2x 8 pin connectors for everything- in/outs, ins with gain reduction, 220/230/110/120v in (it has a built in power supply), and who knows what else?
So far I've really struggled to find pin outs for these connectors, and a schematic for the unit. Does anyone in the brains trust have any leads? They seem to be less utilised and less desirable than the BA-31s, which I believe are fixed gain line amps, and are all over the web.
I was hoping to turn this into a preamp, but a tech in the USA I chased up for a schem suggested it wasn't worthwhile, so at the moment I'm just hoping to get it into working condition and go from there.
