Just finished up this 1972 Gottlieb World Series (AAB version of Grand Slam). Game was mostly working when I picked it up but dirty and not attended to for many years. Backglass was perfect. Playfield had norm wear spots near the kickout holes. A few weird hacks like o-rings for flipper rubbers. A couple of sticky latch relays. I don't know if it was ever cleaned/waxed. Carbon dust was piled high.
Cabinet repair, sand, repaint. Rebuilt all mechs. Cleaning, polishing, waxing, cleaning, polishing. Relay board refinished. New power cord. Replaced yellowed posts and plastic bits. Repaired and clearcoated playfield with 2X.
The game was a good canidate for a total restore since it was bassically in good shape. Two years on route and then stayed with the same family since 1976.
Great project interupted by a project to insulate my garage for future restores. Excellent way to get my mind of the pandemic. Now I'm looking for my next project.
