I have a Summit converted Bally that is starting to exhibit failures of the solid-state relays.
Initially it was the hopper failing to start on a payout unless the unit was cold but now I have leakage on the coin lockout solenoid so it buzzes or remains pulled-in.
My driver board doesn't use triacs in favor of OptoFilm OFA1202 solid-state relays. These are long since discontinued and I can't find drop-in repalcements. I also can't find a diagram for this version of the driver board. I've already replaced one already with a micro-relay board of my own design but they are tedious to build. Is there at least a map of what each one does so I don't have to shotgun the whole board?
