Question about Pioneer A35R 2-Channel Amplifier
Pioneer SA1000 integrated amp - low, distorted output to headphones and speakers. I loaned this out and I believe it was overdriven or overloaded with too many speakers. I replaced all 4 output power xisters with no discernable improvement.
At this point, I would be looking at the main power suply for the final output stage. You may be attempting to drive the output with the driver section rather than the final amp stage. The center pin of the output transistors should have B+/B- on them. Measure that to ground and report the value here.

A little more triage would be in order before you take a knife to it. What source(s) produce the distorted sound? How about test tones? Same? It's sick. Not same? Something else is going on. Have you referred to the manual(s)?
