I am attempting to restore my Astro City I've had for going on a year now. I'm tired of just looking at it and not being able to use it. The Astro was missing most if not all the internals when I received it. I have acquired a Versus JAMMA harness, Naomi power supply, Naomi audio Amp with 12v step down transformer. I am attempting to rewire the cab for JAMMA, my question is do I need a step down transformer for the monitor? I am in the USA so using 110v AC power, I believe the monitor uses 100v. If so where do I find a 110v-100v step down transformer? Any help would be greatly appreciated!
