So I was being an idiot and accidentally put a 13V #912 bulb in a 6.5V #555 socket. It worked for a handful of games but now is not. After putting a 555 bulb in now it doesn't work at all. Theory 1: When I bent the socket down to fit the bigger bulb in, I busted the socket somehow. Theory 2: Some sort of issue with the lamp driver... but that doesn't make much sense to me since I used a larger voltage bulb in the smaller voltage socket. I can't imagine that would do that much harm. I'm not with the machine now, but was just looking for some ideas. Bally Party Animal. Thanks!
