Williams System 3-6 Power Supply

Williams Replacement System 3-6 Power Supply $115.00

This is a drop in replacement for Williams using the System 3 - 6 power supply board.   This board replaces original part number D-7999-xxx.  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, -12V, 100V and -100V Display
  • 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).
