Volume Control replacement: Replace the original low-quality Volume Control with a board designed as a direct fit for the original part assembled with a high quality potentiometer. Choose the correct version based on the sound board installed in your machine:

Type 2 Sound Boards - Replace the Remote Volume Control with a daughterboard attached directly to the sound board. No soldering required! Here is a simple way to replace the volume control on Williams machines with type 2 sound boards. The original volume control is located in the lower cabinet which I found frustrating because I could not simultaneously adjust the volume and the sound/voice mix on my Firepower. Worse, my volume control would only work in a few positions and I'm sure the cut and spliced wiring from the back box to the lower cabinet wasn't a "factory feature".

Type 2 Sound Boards: Remote - Williams System 6 and 7 with remote volume controls (Type 2 sound boards) - use this kit to replace the lower cabinet potentiometer and still control the volume behind the coin door. Simply cut the wires off the original pot, crimp the included header on the cut wires, and attach the new potentiometer board.

Type 1 Sound Boards: 1 Fuse - Replace the Remote Volume Control with a daughterboard attached directly to the sound board. Basic soldering skills needed for installation. For those Williams games with type 1 sound boards, here is a pin-compatible replacement for the original potentiometer that was soldered directly to the sound board. Components made today simply don't fit into the physical footprint of the original part. I designed a small board that holds a potentiometer on one side and outs in the original footprint via header pins. Basic soldering skills are needed to remove the old potentiometer and install the new board.

Type 1 Sound Boards: 2 Fuse - Replace the Remote Volume Control with a daughterboard attached directly to the sound board. Basic soldering skills needed for installation. For those Williams games with type 1 sound boards, here is a pin-compatible replacement for the original potentiometer that was soldered directly to the sound board. Components made today simply don't fit into the physical footprint of the original part. I designed a small board that holds a potentiometer on one side and outs in the original footprint via header pins. Basic soldering skills are needed to remove the old potentiometer and install the new board.

Speech/Sound Mixer: Replace the Speech/Sound mixer on your speech board. Components made today simply don't fit into the physical footprint of the original part. I designed a small board that holds a potentiometer on one side and outs in the original footprint via header pins. Basic soldering skills are needed to remove the old mixer potentiometer and install the new mixer board.

Replacement Regulator: For all boards, replace the linear voltage regulator on your sound board with this efficient switching regulator. This regulator is custom built with legs to fit directly into your sound board and it will operate without a heat sink. Basic soldering skills needed for removing the old 7805 regulator and for installation.
