Bridge Challenger Power Supply

The Bridge Challenger electronic game has a built-in bridge rectifier, and requires 9 V AC from a mains adapter. In this photograph, you can see a network of diodes forming the bridge rectifier circuit. I had an adapter providing 9 V AC, which I fed to the game, and it worked!

Voltage Regulator

This game also has an internal 5 V regulator, which is a good quality one made by the Motorola Corporation.
