Magnatone Schematics

If you have a schematic for an amp and I don't,
please feel free to submit it to me.

Special thanks to Stephen Keller for submitting several of these schematics, Jerry Dragon for the Aug/64 M15 schematic, Mark Storch for the M15 3x8 schematic, and Steve Luckey for scanning and cleaning up the M2 and M14 schematics! Don Garvin recently contributed all the solid-state schematics and many tube amp schematics as well!
