I am sure, my left channel is cutting on B relay, on A both channels work. I opened both relays and cleaned contacts with thin cardboard using contact cleaner and also cleaned all other tone controls and switches...after cleaning both relays work for now, but i think that is only a temporary solution and should be replaced if they are common relays easy to find.

Cool! Just curious! 
Sometimes novices think the relay is bad if it isn't clicking in which is usually a different problem involving the protection circuit.
I am pretty skimpy with my money. I had the same problem with the relay in my Pioneer SA8500ll about 10 years ago. Cleaned the contacts and it is still working today.

Im no expert but if relay won't click that usually is because protection circuit won't let voltage to relay coil, witch means ether the voltage is to high for dc offset, bad bias, or something is shorted, so the amp stays in protection then. Mine works just fine stays in protection for few seconds when I turn it on, then it clicks but with no sound on left B relay, then when I push the B button few times on and off, left ch starts working again. Any tone control witch passing the signal could be suspect but if someone knows part number for those relays ( I forgot to take a picture) of simullar for replacement maybe it could help.
