This is a minimal collection of parts that will fix a design flaw on the early Gottlieb pop bumper boards, plus makes the pop bumpers act quicker and more stable. Gottlieb issued a service bulletin to correct a design error with the PBDB. A great many of these boards were delivered in games prior to correcting the design at the factory. Examine your boards to ensure that they have been updated. A dead giveaway is the lack of a jumper to replace CR1. Shown below are early boards with the error and later boards with it fixed.
See picture #2 and #3 for the different board types. If yours looks like picture #2, you will need this kit, unless you are purchasing the full pop bumper driver repair kit.
Includes:
- (4) 47uF, 16V Electrolytic Capacitor
- (4) 4.7uF, 20V Tantalum Capacitor
- (4) 1uF, 50V Non-Polarized Capacitor
- (4) 10K Ohm, 1/4 Watt Resistor
