Original poster: "Paul Marshall" <klugmann@xxxxxxxxxxx>You can feed them a little higher voltage but not if the secondary is unloaded. For instance I could get away with feeding my neons about 170 volts when I was charging my capactors. This gave me about 21,250 volts on the secondary. The problem is that neons are dry transformers which are center tapped. That is the weak link. Usually what happens is that one of the sides of the secondary arcs to the case and forms a carbon track. This is like a dead short. End of story.
