Replacing a bad diode on a Bally 6803 wedge lamp socket
On these games each wedge lamp socket has its own diode (a 1N4004-type rectifier, not a zener, even if it looks glass). To replace a bad one you don't need to pull the old lead out of the socket: cut the old diode off at its body and solder the new diode's lead to the stub that is left, keeping the band facing the same way. If there is room, the new lead can instead be pushed in beside the old one and soldered.
