Mr. Pinball Tip:

If your solid state game blows the main-line fuse immediately, and violently, chances are that your varistor has shorted. The varistor is the surge-suppressor component on solid state games. It is usually about the size of a dime and is colored red or green. It is wired directly across the main line wires to prevent power surges from going any further in the circuitry and destroying the expensive parts of your game. You can easily test this my clipping out (or desoldering) one of the varistor leads. If the game comes up and no longer blows the fuse, you've found the problem.

Caution: DO NOT run your machine without a varistor. If a power surge hits your machine is unprotected!
