I have an RCA MI12158 PA amplifier that i've decided to restore. Its a pretty sweet 4 channel mono amp, its got some nice triad input transformers I'd really like to hear how it sounds...
I'll be replacing most of the caps and probably a bunch of the pots. I'm having trouble finding schematics for this amp,
does anyone know where I might be able to find some? I shouldn't need them to recap but i'd like to get them for checking voltages and because I'd like to mod it with a preamp output....
this is my first post, thanks for reading, any and all input is appreciated!
I'll post some pictures of it once I get started
