This is because the voltage is so much higher (and the current so much
lower) froma tesla coil than a NST. Try using parralel bars several
inches (or as far apart as the coil will arc) apart. If the arcs between
them are snappy rather than a thick purple arc, try reducing input
power, or change the firing speed if you're using a rotary gap.
>I assume you can only do this with a AC supply like the Neons.
Not neccesarily. If you used a smooth enough HV DC supply, a Jacobs
ladder would wok fine, but no one does this since AC is so much easier
to work with
But a Tesla
>coil output is pulsed DC ( ? )
No, a tesla coil has a high-frequency AC output
so it won't work, unless there is not enought
>( or to much current ).

I belive there is a page on the Tesla Coil webring with info on
someone's current experiments towards the dual sec. single pri. plasma
ball type coil
