Hi Guys,
I have an old RCA SA752 amp, without much of the schematic... I checked and replaced the out of value resistors, and most of the caps,,, Just taking a shot in the dark here, to see if anyone has a schematic for this guy, or has any experience with it...
Regards,
John

If google is no help, sit down with a pad and pencil, and draw up a schematic from the unit. I have done that MANY times over the years. And especially if you already have a partial.
I have tried to trace wiring, and add whats missing on the schematic,,, I took teh partial I have to Staples, and had it blown up, so I could add teh missing components.. I'm not very good at it!!! I ended up with a bunch of erasing...
Also, if I could find an original schem, I would know the test voltages, to confirm my progress...
Thanks for your reply, I'll keep at it...

Nice. I haven't seen plate cap rectifier tubes since my Mother's 1954 Philco TV. Possibly dates from that era, when monaural was was the only channel. I'm sure Howard Sams had a Photofact package on this, but who sells the old ones I don't know.
Thanks for the reply,,, FYI, the caps are on teh output tubes... I believe this amp is from 1962....

Well, I bought it cheap for parts,,, but, it became a project... I sure hope the OPT is good... waiting on some caps, and I still need a 6146A, to give it a test drive,,, its only one channel, so, I guess I can build a 70W kitchen radio, with the tuner I just finished!!

all that iron and only 1 channel, very interesting.
I have a theatur amp PP metal 6L6 tubes and uses a single ended 6v6 with a transformer for extra boost on the voice input. Really weird amp but it is a very loud amp.
