So, I was given a motherfucking Sunn Concert Controller 1 to repair. I've been completely ecstatic just working on it. There's one problem: it is impossible to find a service manual. I've been looking for a service manual for eons---even Fender's official site doesn't have them. Does anyone have a service manual scan or know a place I could get a service manual scan? I've been doing measurements and all that, but I don't know what values are actually supposed to be.
