Compatible in Contact. Disco Fever, Flash, Phoenix, Omni (shuffle), Stellar Wars, Time Warp, Tri Zone, World Cup.
2oz copper. Wide tracks with careful attention to routing of audio signals.
Sounds great with no audible hum.

Comes with the remote volume bypass jumper installed. Games that mount the sound board in the head use the J4 connector for a remote volume control knob that is found in the cabinet. If you want to use the remote volume control knob remove the jumper link labeled "REMOTE VOLUME BYPASS". Volume is adjustable by using the labeled trim pot on the PCB.

Available in my Pinside store and http://nvram.weebly.com

This is a recreation of the original design and not a custom MP3 playback type device.

minor changes include...
2x 4050 signal input buffer became 1x 74HC240
7805 became lm1084
1408 DAC became DAC0808
discreet diodes for bridge
resistor network instead of discreet resistors for input signal pullups.
