So a few weeks ago I had a pop bumper (upper/bottom) coil burn up on my Ripley's. I replaced the fuse, transistor(Q11), diode, and coil, worked great. Then about 4 days later I had smoke coming out of the playfield with another burnt pop bumper coil, this time the upper right one. I guess its possible that coincidentally a neighboring pop bumper coil/transistor could burn up in a short amount of time but I'm wondering if it's actually something else in that coil group causing the transistors to fail. This machine has probably been powered on for 40 hours its entire life. Anybody have any ideas or experience with this issue?
Thanks
