Re: Help with strange audio fault #qcx

I am suspecting a capacitor issue in the audio circuitry or earlier in the signal path.
Ted,

I'd suspect a dry joint somewhere. Maybe a capacitor charging up when it should not? Component faults are rare, construction faults not so.
But whatever, start with checking voltages against Hans' chart. Use the built-in meter. It might take a while as the fault is intermittent, maybe a good look at joints?
