Note: Please Read

Warnings: This board contains hazardous voltages. Never touch components on board with machine plugged in! This board includes parts that normally operate at high temperatures (roughly 200F). Never touch board until components have cooled off!

This circuit board requires de-soldering wires from the old board and then re-soldering the wires onto the new board! You need to take extreme care to track which-wire-goes-where. We DO NOT recommend that anyone but the most advanced repair technician try to use this board!

Note — not all machines are fused the same. Refer to your game’s manual for proper fusing.
