Original poster: "R. Bergmann by way of Terry Fritz <teslalist@qwest.net>" <bergmann_@hotmail.com> I have used the same method in my tesla coil. Mine puts out a max of ~1.5-2 foot streamers with a 120bps sync rotary and a 15/30 NST. Is this sub-par? I don't know! I never look at the lengths that you are "supposed" to get with a 15/30. Ryan _
