Lot of original Williams System 3-7 pinball machine circuit boards. This listing includes two power supplies that are in good used condition. They both appear to be complete, but see photos to be sure. Also included is a driver board (part #1B-2001-131-2) that does have a hole in it from and is missing its relay. MIght be more of a parts board. Again see photos for more details on its condition. We found it in a box of spare boards from a cleanout.
Boards are sold as-is, presumed not to be working.
