I would probably start with looking at the 0-9 unit .. good contacts etc, and the relays for the 3 Jokers, and any 'Series' relay I could find. On some machines there's a small plug connect which gives the option of 'replays' or 'no replays', but if it's popping on score, then it's probably not that anyway. ... Good Luck. I really like this machine. Mark
