Hi....Need some help with a yard sale amp. Picked up a Kustom 30RC for five bucks this past weekend. Someone had unhooked the switch and transformer wiring. (4 wires) I can't find a schematic anywhere..really frustrating..I know it's not vintage but seems like it might be good for one of my grandkids. I have a cpl older Kustom amps but the wiring is nowhere near this. Maybe if someone has one of these and can post a pic of the wiring or where I can get a schematic I would appreciate it..Thanks
