Quoted from michiganpinball:I repair "the pin" games in peoples homes. We pinheads complain about them but the home game room buyers like them. They buy them from a game room supply chain and get it delivered and set up in their home. They get white glove treatment. They have fun with them and have no trouble getting service through the retail store.
I have been servicing just about all pinball machines for over 45 years. It is important to have service documentation like schematics and parts diagrams/lists so that us service techs can fix these things quickly and order the necessary parts if needed. Where on Stern's website is the link to the manual, schematics, score cards, switch matrix, coils chart, etc?
