hi ron,
over here on the errmmm, more cultured? side of the pond our teslacoils play bach.
http://www.youtube.com/watch?v=H7bC59SnFCkfinn brought 0ne coil from the six over to the cambridge teslathon a couple of weeks ago which i organise. if you have ever stood next to a working tesla coil you will know how loud they are. took me a week to get the sound out of my head. i am sure if Tesla was alive today he would be in there programming the midi, and shouting MORE POWER!!!
anyone interested in this sort of stuff have a look on the 4 HV.org newsgroup.
have fun
bob golding
