System 11 Auxiliary Driver

Plug and Play! 

Williams Replacement System 11 Auxiliary Driver No Longer Produced

This is a drop in replacement for Williams and Bally pinball machines using the System 11c auxiliary driver.   This board replaces original part number D-11813 and D-12247.  The benefits of our new board include the following: 

  • Plug and Play replacement
  • LED lights for fuse and supply checks - gives instant status for all fuses on the board.
  • Thicker boards for more stability to help reduce stress cracks
  • Heatsinks added to bridge rectifiers to keep cooler and last longer
  • High quality 105C capacitors used for longer life
  • As with all Kohout Enterprise boards, only through hole components are used (No surface mount)
