[TechAssist] Kustom KPS-PM100 powered mixer

I've got a lady bringing in one of these PA amps sometime tomorrow, and she
needs it back by Saturday for a job they have.

The symptoms are 60Hz hum after it warms up (which can't be turned down),
and chirps/squeals sometimes when they turn it on.

I'm 99.9% sure I'll find some bad electrolytics, but would anyone have a
schematic for this just for standby backup? I've searched around on the web
and have not found anything.

Thanks,
