I contacted Kurzweil and got no reply (yet). Anybody have a schematic for one of these? I have one with no/low output.

Used to have that one, but not now. Call them on the phone.Education is what you're left with after you have forgotten what you have learned. -
Called and got voice mail- left message. Emailed- no reply. I will certainly keep trying, but I thought in the mean time......"I took a photo of my ohm meter... It didn't help." Enzo 8/20/22Comment

Drewline,
Firstly, thank you so much for the uploads. I'm in the middle of an all day recone project, so I will have a good look at those as soon as I get a second. I took a quick glance through them and don't see the portion I need which is the I/O board. I have traced signal on to that board, so I believe it's somewhere there- possibly a muting circuit since all op amps and transistors appear to be good. Without a schematic, I'm not sure what's supposed to happen, so I've been trying to decipher the circuit without one. The info I need may well be in your uploads and I just missed it in my quick scan. There is a troubleshooting guide in the PC88 SM, so I'll take a run at that. Again, thank you!"I took a photo of my ohm meter... It didn't help." Enzo 8/20/22Comment

I'm not sure what the second half of the PC3 manual is doing with the PC88 manual, but I'm attaching the first half here in case it might be of some help. In any case it gives you the entire PC3 manual.
