This amp was completely re-built on a hand-drawn printed circuit board. The circuit was more-or-less stock, and most of the original components were re-used as well. I have no idea why someone did this. Maybe the old fiberboard was heavily damaged.
Also, the underside of the new boards were completely covered in silicone! Instead of trying to remove it all just to replace a few electrolytic caps, I rebuilt the power supply inside the chassis and replaced a few of the signal caps on top of the board. I also fixed some ground loops caused by the new boards and reverted the circuit to 100% stock specs.
Despite the oddness of this amp, it actually sounds just like any other Blackface Bandmaster.
