Question about Peavey Music
Is this repairable without a schematic?
Potentially. Capacitors are what prevent the DC component from flowing through the amplifier where you want only AC, so it is pretty brutish and easy to find.
It likely is a failed zener diode, or a failed bridge rectifier, or single rectifier depending how they chose to do it. Since it is isolated to the inputs, that is where it will attach. Either to pin 2 or 3 on the XLR. It will be isoalted from the preamp by a capacitor on the order of 0.1 microfarad to 0.01 microfarad. It might be higher, but not likely.
If replacing a Zener, match for voltage, but go to a higher current type. If replacing a 1 amp bridge rectifier, go with a 3 amp if there is room. If replacing an 1N4001/1S4001 go to a 1N5403 or higher voltage rating even.
