Had an issue today with my Flinstones. Decided to illuminate the buildings and up the top end of the playfield etc and it looks great. Problem is that 1 of the lights is real close to a ramp switch and when the ball triggered it, it blew a fuse.... no worrys just raised the shops a touch, replaced the fuse and all good.... so I thought. Lost a line of switches. after tracing the switches it may be u19 Ic Lm339 Quad comp. But not to sure. Took out the left hand ramp return switch, G switch, left bowling switch etc.
