24 piece electronic components rebuild kit for the High Voltage section of Williams A-14039 WPC system dot matrix controller boards.
This critical update kit is designed to prevent burnt circuit board damage from original components. Take a moment to inspect the rear side of the A-14039 controller board and you will see a blackened area under the high voltage circuit area.
Installation requires circuit board soldering skills and about 20 minutes.
NOTE:In some game manuals, D4 and D5 are correctly listed as 1N4758A, but incorrectly reference these diodes at 62V. The WPC Schematic manuals correctly lists these diodes as 1N4758A - 56V.
