I'm fairly new to collecting machines, so I'm not sure if this is a common problem or something you can fix, but I just bought a Namco Ms Pacman/Galaga machine and after playing for a bit, noticed you can feel a bit of electricity from the screws/pins around the controls. It's not much and doesn't hurt, but it's still a bit annoying cuz you can't rest your hand over them without feeling a little electricity.
Is there a way to fix this? Is there some sort of grounding issue? Maybe static from the monitor?
Thanks!
