Default Denon PMA-770 problems

Right side works, left side not, unless volume is set way high, then
horrible staticy low volume. All output transistors removed & checked, all
good. Any ideas? Otherwise it's gonna get tossed, or maybe Ebayed for
parts.

Check the emitter resistors and that the speaker relay is working
correctly - it could have bad or damaged contacts, even just on the one
channel.

For that matter, check for any other possibly burned resistors. Could be
loss of voltage to the driver transistors on that channel.
