View Full Version : Guide for adding 12Volts to a JPac

28th December 2007, 08:33 PM
Was looking around for a simple solution to add 12v to my MAME setup, (for a mono amp) and found this mod for the JPAC.
Nice and simple and puts the 12v in a convenient spot.


WARNING : Always make sure the Jamma plug is the correct way around to the JPAC if leaving the PSU plugged in. As 12v to the wrong part will damage the JPAC
