Information
I Haven't had much action around these parts lately, and the channel switching in this bad boy started acting up, so let's get the trace show running.
I haven't seen schematics for these elsewhere
First up: Board A - the preamp board.
Board B contains the power amp and tube driven effects loop. I'll take photos of it as soon as I finish tracing board A.

Looks like they have quite a bit in common, though it seems this PCB accomodates circuitry to switch between a solid state or tube buffered effects loop instead of multiple master volumes
Here's the work in progress. It's linking to my dropbox, so this will always be the latest revision.

The preamp board is pretty much done - this was a messy bugger to trace out. When comparing it to the Mesa and Soldano amps I've otherwise worked on, even the japanese SP-77 knockoff sports a nicer PCB layout
