Title: Fender m80 4x12
Post by: Stevendean18 on September 15, 2020, 10:24:38 pm

Hello, my name is Steven and I'm new to amp stuff. I have a fender m80 that doesn't work right only has super low volume. Opened it up board shows that 2 capacitors are burnt. At least I think they are capacitors. I'm trying to figure out how to determine what the hardware is and how to find replacement parts. Does anyone have a schematic for a 1989 fender m80 4x12?

Welcome.

This is for a "M80 Bass", but I bet the electronics are 88% the same, the main diff the speaker?
