Its a Williams Tri Zone. Early Solid State. Pops, slingshots, drops, a spinner, kickout hole, multiplier bonus, etc. If i were to service the boards fully with new molex connectors, new chip sockets, new power resistors, and new filter capacitors, along with rebuilding the flippers, pops, new rubbers, bulbs, power cord, and coil sleeves, how much could I get for it? The backglass is near immaculate, the playfield is good except for two small wear spots above the flippers (no bare wood), and the cabinet is in above average shape.
