Original Brunswick air hockey game control circuit board that is untested. We found this one in a warehouse cleanout, we have no way of testing it. Board is missing a component at Q3 (transistor?). Original part numbers are 51-201213-3 REV. 5 / AIR HOCKEY CONTROL BD.
We do believe it is still usable, but may need to be repaired. We have no means of testing it.
