I have a few pictures of the schematic downloaded from old eBay listings that ended. I didn’t want to spend $100 on a drum pad I probably can’t fix just to get the schematic. I wonder if anyone has the schematic to save the effort or if someone would have pictures of the PCB. I have heard the original schematics are hard to make out.
