Original poster: "steve" <steve_vance-at-cablelynx-dot-com> Got a question for the list, I'm looking for a new project to start. I am thinking about building a small 2"orbit powered coil. My question is has anyone ever built a Tesla coil with a square primary or secondary? Is there any reason that this wouldn't work? Steve Vance http://fire.prohosting-dot-com/~bonestc/index.htm
