Having issues with the pop bumpers,slingshot kickers,&out hole kicker. The flippers work and the eject ball into plunger lane works properly. I have been doing my research and found the pinwiki site and other info on forums here. Lots of talk about the transistors being bad at the Q309,Q310. My sound is also not working getting the scratch sound when turning the sound up and down. Any ideas on where to start? As always Thanks for help and info
