Hi everyone, I'm very new here, in fact first post. I wasn't quite sure how to start a new topic so I'll start here.

OK, I have managed to pick up a YAMAHA SB200 Effects box. It's had a bit of mangling along the way but I hope to restore it to near original condition.

I've kinda trawled all over the internet for the cct/wiring diagrams but no luck except for some photos etc, and of course, this thread.

It's not the individual pedal schematics I'm after - that will happen later, but the system board. There are a couple of cut wires and small mods been made and no bother testing until wiring is confirmed I guess.

Any help would be appreciated.

I've added a couple of photos to make you squirm at the disrespect some people give to such fine electronics!!!

enjoy

Thank you rcustoms! Exactly what I needed.

As I suspected, there are 2 'CANS' seen in my second photo that don't appear to be in the schematic.
I guess it was an add-on by a previous owner, possibly impedance matching? One wire is cut anyway..
And the mounting bracket certainly looks like it did NOT come from Yamaha

Anyway, I'll stick to the easy stuff for now and attack this wire mess later.

I'll keep posting photos if Anyone is interested in how it's getting along. Might be some time though.. gotta work on paying stuff first. blah blah.
