yes NPN and PNP ... obviously not interchangeable .OK, now I feel stupid. I didn't notice the difference between the 2SA484 and 2SC484 driver transistors

Ah, ok. I found these on Mouser--they're 100 ohm, so I'd have a bit more range. Is that a bad idea? Should I stick to 50?
The outputs all test good.
I agree! I sold my SA-1000 not tat long ago, and truly miss the sound it had...... great eraGood job on finding the cause. They are a beautiful amp and were TOTL at the time, l wish l still had the one l let go about 18 months ago. In my opinion they make the ever popular Marantz 1060 and others sound lacking in comparison.

The trimmer thing was important--I think I had to up the 50-ohm to 100-ohm and may have had to increase the others as well. Otherwise just swap caps and transistors. Those boards are a CHALLENGE to work on--lots of wires to break, lots of weird solder connections with multiple parts in them. If you know what you're doing, you are good. I had no clue when I got into that one, so it was not easy. It had also been messed with before.
