Glad you got it fixed. I had dug out my schematic yesterday, but got drowsy and never got around to studying it.
Playball is an interesting game. Mine plays a little on the easy side, even with the posts set to conservative and the replay levels on the highest manufacturer's card, but it is still fun. I like that it has both a chime box and a large bell (for the runs scored). It is also not unusual to achieve the replay levels for both score and runs nearly at the same time and be able to hear "pop, pop" at the same time that the large bell gongs. Cool sounds!
