Do you think an arcade power block could be used. I don't have the specs on me, but I've got two of those from an NFL Blitz and a SF2. They have both 12v and 5v and I had planned on using them to power my leds and what not. I guess my question is, is it the amparage of the power unit that is the biggest concern, (as I'm presuming that 12v is 12v either AC or DC)?
