Quoted from bdPinball:Searching for a Ball Count Unit (and advance if we get that far) for my Williams Blue Chip. It's an Add-a-ball, 76, and it's slightly obscure. Fun game though! Just wish it would give us EXACTLY 3 or 5 balls, not 4, or 7, or sometimes 6!
Thanks in advance..
I'm sure someone will ask, but Yes, we checked with Steve Young, and his words were I'm told, "Good Luck with that one."

I don't know. I don't think you need replacement. Misaligned steppers maybe. I've worked on dozens of EMs and never once had to replace a component. Desolder the units, move them to the bench and disassemble them. Those shafts need to be cleaned up and moving freely. All the contacts need to be swiped with q-tips dipped in alcohol. All pieces of the unit should move freely "dry." No grease or lubrication.
PS: I only clicked on this because I love Blue Chip. I'm always keeping my eyes out for one. Good luck.
