"Hello All:
        With AC resonant charging, the maximum attainable voltage is pi
times the peak AC voltage.  This can occur after 1.75 cycles of the AC. 
If
your spark gap is set to fire every 1/2 cycle and misses a couple
firings,
the voltage can rise to extraordinary values: 10 kV x 1.414 x 3.14 =
44.4 kV
peak!  (So long, NST!)
Regards,
Mark S. Rzeszotarski, Ph.D."

Mark:

	Please explain that remark.  Around here the maximum attainable
voltage, assuming no breakdown in either the gap, transformer, or
capacitor is the transformer Q at sixty cycles times the open-circuit
voltage, and I've satisfied myself to that by operating a transformer at
low voltage.  The Q is certainly greater than pi.
