I have one of these on my bench (one channel is lower than the other). Does anyone have a schematic for this amp?
Ok, it seems a schematic is not to be found for this integrated. I'm not bad (and getting better) at troubleshooting solid state stuff WITH a schematic, but I have very little experience with tube amps. Add to that the absence of a schematic, and I'm in for rough sledding. So if anyone is willing to guide me through signal tracing the cause of the low left channel, I'd be grateful!
Loooking at the pictures I think the power amp guts will be similar to the 9100.
I couldn't find schematics for that either so traced and posted here (post #7).
Aronov LS9100 - any info ???
Cheers,
Ian

Your schematic was a big help. Turns out the cause of the channel imbalance is the left volume pot. Unfortunately, the original Bourns pot used is obsolete, and an ROHS replacement exists but isn't stocked by anyone. Still searching, but doesn't look good.
