Digging through the archives, realized I may not have posted as much in the way of process from our past projects as I had originally intended.
Here’s a peek at how thorough I am with my work in regards to electro-mechanical restoration of the custom games we produce. Specifically, this is the analog motherboard, brain and guts, score motor and relay banks, from a 1974 Gottlieb Top Card before, during, and after complete overhaul, full restoration.
I remove the entire brainboard, unseat all wiring, then proceed to file and clean all switch contacts, checking their position against original game schematics for reference after retightening all switch stacks back down. Once the score motors and relay banks are all cleaned and tightened, I sand down and shellac their host base, and then begin reassembly for testing.
Assemble, tighten, dial. Test. Run. Dial. Test, run. Dial. Test run. Run. Run. Run.
Removing 40years of wear and tear, restoring a classic pinball machine, and then tricking it out custom, no shortcuts taken.
