Default Re: Onkyo SKW-591 subwoofer is dead

You could check the voltages on Q501 and see what they are but looking at the ic' pdf the voltages on the output side seem to be referenced to com (pin 10)
I'm not sure why there is +2 volts on VS, it could be coming from Q501 or it might be normal, there is a difference in resistance from VS to positive supply (42.1k) and VS and negative suppply (44k) and that might explain the +2 volts
