John, I must agree with your "intuitive sense"! I does seem probable that
the intense heat formed from CW VTTC (even pulsed) will provide a intense
(hot!) ion path for sparks to follow. Thus reducing the potential growth
Perhaps a "Super Staccato" VTTC could produce similar results as a Spark
gap coil (at least research wise) with less burnt Silicon, ;-)
