Williams System 7-11b Power Supply

Williams System 7-11b Power Supply $115.00

This is a drop in replacement for Williams pinball machines using the System 7 - 11b power supply board.   This board replaces original Williams part number D-8345-xxx or 117667 and Data East Part Number 520-5000-00.  The benefits of our new board include the following: 

  • Plug and Play replacement
  • Measure your power supply voltages and instantly check status of the fuses without using your meter!
  • Added voltage meter for the 5V, 12V, solenoid input, solenoid output, lamp input, lamp output, display positive and display negative voltages.
  • LED lights for instant supply and fuse status checks
  • Thicker boards for more stability to help reduce stress cracks
  • Optional jumpers for 100v or 91v display settings
    • 91v settings are used to lower power consumption and lengthen the life of the original gas displays
    • 100v is the setting used on the original boards
  • Circuit adjustment for HV display to waste less power
  • High power resistor updated to flame proof Metal Oxide as recommended by most repair guides
  • 5V regulator updated to High Efficiency Switch Mode Power Supply
  • Heat sink added to bridge rectifier to keep cooler and last longer
  • Update obsolete components to current production parts
  • High quality 105C capacitors used for longer life
  • As with all Kohout Enterprise boards, only through hole components are used (No surface mount).
  • Screw terminals have been installed for the General Illumination power connection (blue connector, bottom right in picture below).  You can either screw your power directly to the board or use the supplied 4 pin connector.
