Roland KC-300 print

[guitardad]

Anyone have this? I have the KC500, 350 and others but the KC-300 is different. Unit came in with cut jumpers from the i/o jack board and preamp. I think I can just direct wire them. I managed to find the KC300 amp schem, but the preamp section schem wasn't part of it.

Guy said he gave it to another friend to fix (3 mos ago), but the guy couldn't find the jumpers.

Thx in adv.

Compare this schematic to your amp and tell me if it is the KC-300. I have this marked as KC-300 and it shows the preamp section. Let me know...

I don't see a preamp?

That's the main amp section. I have that section. I need the preamp and IO daughter board.

Here is the preamp schematic.
