(Another) sa-8100 restore

[Fusion 101]

Hello. I’m attempting a restoration of a Pioneer SA-8100. It is not in terrible shape, and I did a thread on restoring the wooden case. In that thread I indicated how the amp went into protection mode after I treated the switches and pots w contact cleaner. Now I’m at the point where I’d like to follow the prescribed restoration procedure. I’ve procured replacement transistors and some caps (thanks mattsd for the list on this thread http://audiokarma.org/forums/index.php?threads/sa-8100-protection-circuit-issue.777758/page-2) but am not finding the board diagram for the “D” revision boards. Can anyone please point me in the right direction?
Thanks in anticipation of your help,
Luis

Thanks Finnface, that is an excellent thread and will follow for the next batch of replacements on my 8100.

I replaced the two 1451s and the four 726s on the power amp board and it came out of protection and played all night long (at least four hours straight, no glitches). I’m very happy (and hungover). I will continue with replacing the rest of the 726s and a few caps later on.

1451 replaced w 3503
