Default Zapco Studio 54 schematics?

Does anyone have a schematic or a user manual for a Zapco Studio 54 amp?

I have one given to me by a collector friend (9.5/10 cosmetically) and opened it up to find leaking electrolytics inside. took em all out but haven't bought replacements yet. I was curious about how the circuit works so I hope someone has a schematic somewhere.

I also want to see the manual for complete specs of the amp as the only thing I know is what my friend told me that it puts out 4x5wrms which is tiny.

yeah I figured that out when I checked the datasheet for the chip amps. still, a schematic and manual would be nice as I'm curious about the feedback taken from the speaker terminals. Seems there is a circuit to lower distortion of the chip amps.

never thought about that. I just emailed technical support. I hope I get a useful answer

edit: I got a reply within minutes from tech support with the schematic diagram. no manual but it'll do. Very fast technical support!
