Nathan -

So this is not an NST at all, it is a 15KV, 1ma (that's ONE milliamp) DC 
power supply. And it was driving a coil producing 26 inch arcs? Absolutely 
incredible performance, better by at least a factor of 10 then any other 
Tesla coil ever built.

Please be so kind as to share the construction details with us
