Could be although I still reckon high voltage kickbacks are the major
problem. Any NST matched to the TC primary cap for resonant charging
will tax the current limitation of the windings. I can run coils
quite happily for several minutes at a burst on NSTs. Resistors will
de-Q the charging circuit somewhat.
