That Model number is hard to see. "25 E-25" and the Serial number starts with "H-57nnnn" When I was looking for the Model number I discovered why this thing came into my possession along with a boat full of junk. Someone has removed the foot-stomp switch. The Bracket, screws, switch and all are gone. Wires are cut. That switch must have failed and the guy intended to get a replacement....That was years ago though. Now I gotta figure out what to do next. Any ideas?
