Steve,

The term "LTR" means "larger than resonant", but you're correct
the frequency will be lower than resonant.  However, it refers
to the resonant frequency of the 60Hz *charging circuit*, not the
resonant RF primary tank circuit.  Tank tuning is a separate
and different issue, not addressed by the LTR issue.

By running LTR, the resonance of the charging circuit is killed,
and the NST voltage can not resonantly build up, in case
some firings are missed.  Also, since the cap value is larger,
a lower voltage will still provide that same bang size.  This
lower voltage puts less stress on the NST.

Cheers,
John
