Hi all, I have a 1980s Peavey Artist (100 combo with Black Widow speaker). Very weak output at volume, I think it might need new valves but have no way of testing them apart from taking them somewhere & paying for the service, which I want to avoid if possible.
Would you have any basic service or "testing "procedure I can follow to try & identify the cause of the weak output?
I am well aware of the potential high voltages stored in the capacitors but am keen to check the condition of the capacitors. I haven't had the chassis out yet to conduct a visual inspection for leaks etc. Can you suggest a setup I can make to test/drain any residual voltage in the caps? Can I use my multi meter and if yes on what setting?
Many thanks in advance, Mark from Sydney, Australia.

Check for an effects in/out socket. They can get tarnished contacts and cause low/poor output levels.
