A-12697 WPC Power Driver

Old Power Driver Boards fail. A lot.
Fried GI section, random resets, weak 5V power, cracked solder joints, worn connectors, ageing bridge rectifiers, swollen or leaky capacitors — after decades of heat and stress, original boards are simply at the end of their service life.

Fits:
Black Rose, Bram Stoker's Dracula, Corvette, Creature from the Black Lagoon, Demolition Man, Dirty Harry, Doctor Who, Fish Tales, The Flintstones, Funhouse, The Getaway: High Speed II, Gilligan's Island, Harley-Davidson, Hurricane, Indiana Jones, Indianapolis 500, Jack*Bot, Johnny Mnemonic, Judge Dredd, The Machine: Bride of Pinbot, No Fear: Dangerous Sports, Party Zone, Pinball Circus, Popeye Saves the Earth, Red & Ted's Road Show, The Shadow, SlugFest, Star Trek: The Next Generation, Terminator 2: Judgment Day, The Addams Family, The Addams Family Gold, Theatre of Magic, Twilight Zone, White Water, Who Dunnit, World Cup Soccer '94

Even repaired originals can be a gamble. Removing the five large capacitors often pulls out the plated through holes, leaving hidden open circuits or ugly wire patch fixes. And the LM323 regulator at the heart of the 5V supply has been obsolete for years, running hot and stressing the transformer, and contributing to game resets.

Our replacement board eliminates those problems.
• Modern 5V regulator — cooler, more efficient, no heatsink required
• Factory set 5.1V output — stable, adjustable, rock-solid
• Improved GI section — wider copper tracks and more effective TRIAC heatsinks
• Original Williams ground return path design preserved — exactly as Williams designed
• Supports -1, -3, and -4 variants of the same board
• Brand new PCB and connectors — no more chasing intermittent faults
• Authentic schematic correct design — component placement, routing, and connections closely match the original
• Fully tested — ready to drop straight in

This board is a clean, drop in replacement that behaves exactly like the original — same timing, same logic, same feel — but built with fresh silicon, clean copper and decades of reliability ahead.
For restorations, long term reliability, or machines that see regular play, a new board is often a better solution than continuing to patch an ageing original.

Replica board made by MC Circuit Works – not an original Williams/Bally part, and not made or endorsed by them. Part number A-12697 is shown so you can check compatibility.
