WMS DE Bridge Board

Bridge Board – Fused Upgrade for Williams & Data East
Safety-upgraded bridge rectifier & capacitor board

This is the popular Homepin / Inkochnito Bridge Board. It replaces the original unprotected bridge rectifiers and capacitor found in Williams System 3 through 11A machines and many Data East / early Sega games.

The original design had no fuses on the 18V lamp and 34V solenoid circuits before the bridge rectifiers. When a bridge failed it could short, burn the wiring, or in some cases catch fire. This board fixes that design flaw by adding proper fusing, upgraded bridges, and a new capacitor — all on one easy-to-install board.

Key benefits:

• Adds fusing to prevent short circuits and fire risk
• Replaces the old bridges and filter capacitor
• Indicator LEDs so you can quickly see power status
• Straightforward install – no soldering required in most cases

Fits a wide range of classic solid-state machines (Williams System 3–11A and compatible Data East / Sega titles).

A simple upgrade that protects your machine and gives peace of mind.
