Stealth PCB Williams/Data East System 3-11A Power Supply

A Modern Power Supply for Your Classic Williams & Data East Pinball

The original power supply is often the weakest link in a classic pinball machine. After nearly 40 years, aging components can lead to game resets, flickering lights, and even damage to your expensive logic boards.

Our Stealth PCB replacement was engineered from the ground up to be a reliable, modern solution. It's a true drop-in replacement that not only provides stable power but also adds protective features to safeguard your investment for years to come.

Why it's the right choice for your game:

• Built to Last & Easy to Repair
  For power supplies, we use high-quality, through-hole components instead of surface-mount parts. This makes the board incredibly durable and means that if a component ever fails down the road, it can be easily repaired by a technician (or you!) with basic soldering skills. This isn't a disposable board; it's built to be serviced.
  
  
• Cooler, More Efficient 5V Power
  The 5V circuit, which powers your game's sensitive logic, has been completely redesigned. It uses modern, high-efficiency components that generate very little heat, reducing stress on other parts in your backbox and delivering clean, stable power to your MPU.
  
  
• Smart Overload Protection
  This is a big one. If a short circuit occurs elsewhere in your game, our board will automatically shut down the 5V rail before it can damage your expensive MPU or driver boards. It's a simple feature that can save you from a very costly repair.
  
  
• Find Problems Fast with Diagnostic LEDs
  No more guessing or dragging out the multimeter for basic power issues. On-board LEDs give you the status of every voltage at a glance. If a fuse blows or a voltage is missing, you'll know exactly where to start looking.
  
  
• Extra Power for Mods
  Need a spot to power that new sound mod or LED strip? We've included several extra, clearly-marked 5V and 12V auxiliary outputs right on the board.
  
  
• Easy Drop-In Installation
  This board is designed to fit perfectly using the stock mounting hardware and connectors in your game. No special modifications are needed.

What's Included:

• 1x Stealth PCB Power Supply Board
• A full set of new fuses comes pre-installed.

Important Note: Please double-check your game's manual to confirm the correct fuse values are used. Some games in the list have slight variations.
