With my TX-8222 the volume output has become wildly inconsistent; both radio and other source.
1. Very slow to come on. If I push it up (dial) it will come on when it reaches LOUD, and then stay on when lowered to usual listening level.
and/or
2. Sound will come over one speaker and then suddenly shift to the other, at a slightly different volume, and back and forth; no regular timing. Sometimes I do get both.
I did take it for service when this first happened, and they found nothing wrong. Assuming it is not the speakers, I have no other ideas of how to explain or diagnose. System has been working with no other issues for 10+ years in place.
Any thoughts? Complicated fix or a simple cleaning?
