This is on for a full refurbish to get working. 2 balls for 25 cents. Uses a hidden 3-reel Bell-style slot machine as the main mechanism.
Updates:
The mechanism has been fully disassembled and the parts washed. Cleaned with lacquer thinner, wire brushed, and wire wheel. Assembled with 3n1 oil where needed and white lithium grease where needed. Adjusted mechanically to be smooth operating. The electronics have been cleaned. Now I can see the wire colors.
Next, clean the switches and adjust them as needed. Capacitors to be replaced. Solenoids are to be cleaned and adjusted.
The cabinet is now in the shop for a good cleaning. The cabinet will get a new flayfield glass. Wood to be repaired where needed. Maybe some re-chroming here and there.
