An LTR cap can pull more than rated power out of certain NST's and
a resonant value cap can do the same thing.  Much depends on
the particular NST and the LTR value.  Using 140 volts input instead
of 120 volts will also cause more power to be drawn.  In some
combos of NST and LTR value, with a SRSG, the coil may run in
a so-called "reversal mode", in which the VA draw will be
exceptionally high.
