I have a couple of questions on repair. I have replaced a flipper coil and found that the plunger collar is shot along with the return spring. Where can I buy these individually, I typically see kits? I am also looking for the blue plastic posts that are all over the playfield since some of them are cracked. Lastly, I have some lights up around the eight ball and the multiplier chutes that flicker or only come on when the ball hits in that area fairly hard. Would you think this to be corrosion in the sockets or a short in the wiring or something else? I'm thinking about cleaning some of these sockets and/or replacing a bit of wiring here and there. There are some other issues with things like the special lamp staying lit but I don't want to ask too many questions at once. It's my first machine and I am taking it a bit slowly. I have access to great soldering equipment and some very good electrical expertise (father in law is retired electrical tech from Rockwell), just not with pinball machines. I have the manual with all of the schematics. Thanks and sorry for the multiple questions.
