Gottlieb System 1 - Ni-Wumpf Driver
Model: Ni-Wumpf-Sys1-D
 $84.95USD 

Description

Features...

The problems associated with the original Gottlieb driver board are numerous - connections to the CPU can be corroded and cause poor driver/lamp signals; the MPS-U45 is a very difficult transistor to find; and the old 2N3055 transistors burned holes through the PCB. Ni-Wumpf has redesigned the System 1 driver board to address these issues, and adds in a few more features that should prove useful:

  • Each solenoid has fault detection circuitry that identifies failed playfield/driver board components
  • FET solenoid transistors
  • Higher rated transistor components for all circuits
  • Discrete components for easier/less-expensive service repair in the future. Using a transistor array is neat, but costly, when one lamp in the array fails!
  • Modern component architecture uses currently available parts for easy field service - only parts that do not normally fail are surface mounted
  • Diode isolated grounding to prevent playfield lamp problems from the board
  • You can add a Keystone 7691 Ground connector for the recommended Gottlieb Ground Upgrades

Each driver circuit is equipped with fault detection circuitry and LED's to indicate circuit failure.

 

Note that the LED will remain lit when a game does not support the associated playfield driver components.
