Partlist

Resistors are 1/4W 1% and capacitors are 2.5mm pin-spacing, unless otherwise specified.

Capacitor references are only provided for convenience as suitable parts. Cheaper alternatives may exist.
References in bold have been tested. Feel free to report other successful matches :)

Finally, dont forget you will also need a JAMMA harness.
