New to the hobby, and to the boards.
Recently purchased a 1964 Tiger Shuffle Alley in perfect-ish working condition. Lugged it up a flight of stairs, drove it 500 miles, nearly killed myself getting into the basement and.... now it doesn't quite work right.
It appears the M, N, O and P playfield switches are not firing, making it impossible to get a strike. Everything else, including scoring, seems to be working fine. It seems like this could be an easy fix for a competent collector. Unfortunately, that's not me. Can anyone offer so basic help on this?
