Hi,
I've got a Pioneer GM-2200 amp that I bought recently, it is not working as it should - gives DC voltage on both speaker outputs.
PCB looks ok, I can't see any burnt components.
Any pointers on how to find the fault?
It was 20 years ago since I last did any trouble shooting in electronics, so can't remember much about amps... Would appreciate some help.

How much DC voltage?
Was the voltage measured directly across the two speaker terminals for each channel?
