I have 7 Bally machines of this era, from Strikes and Spares through Centaur. Do all of them have this issue and will this board set address the issue in all of them? I was hoping to convert them all eventually to LEDs.
Do other manufacturers from this era have the same issue? For example, I also have a Gottlieb Devils Dare and Williams Pharaoh and Solar Fire. Will they take LEDs fine or would they exhibit a similar issue?
Ultimately, I would take one of these for each applicable machine (up to 10).
