S.o.s M80 Fender Chorus Amp

[ASIK]

Hello to everyone,

My old amplifier broke down and I can't get a hang on the problem.

It seems to be occuring near the ondo or power.

If could please send me the schematics at frenchrows@hotmail.com.

Sorry I don't have the schemo's at this time but the amp is pretty straight forward. Almost certain you have a transistor issue or op-amp. Check the +/- rail voltage for the op-amps and check the collector voltage to see if something is dragging it down and check the output transistors for shorts. The board is not hard to take off. Theres six screws on the bottom that hold the heat sink on and that slides out then mark and pull the connector and a few standoff tabs and it's out.

Hope this works.
