OK, so you agree with what I said.

Cool! That must have been one seriously big cap. What
was the capacitance, ballast inductance, power level
etc?

The coil I'm talking about is a DRSSTC, so LTR/STR
don't have any meaning, as far as I know. But larger
capacitances do seem to work somewhat better. They
give a higher primary current, so you can achieve the
same spark length with a shorter RF burst.

That makes it more efficient, because if the burst is
too long it mostly heats and fattens the spark rather
than lengthening it.
