Matt D,
Perhaps I should have been more specific, a change in frequency  does 
not step up the voltage, but people (like English and History  professors) 
understand this concept better than trying to explain how a  true resonant 
circuit works by capacitors and inductors shifting phase,  and one charging 
by current and the other by voltage, etc.  And no,  the Tank system does not 
step up the transformers voltage, but the  resonance allows a potentially 
much higher voltage to be generated in the  spark gap than what the 
transformers are capable of alone, so as far as  the layperson is concerned, 
the resonant system is making the transformers  put out more.  This is not 
correct, but without going into  excruciating detail (that most people don't 
actually care about or  understand) you cannot easily explain it any other 
way (they just don't  get it!).  Thanks.

Hi Scott,
 
    Was it Prof. Mark Zemansky, late of CCNY, who said,  "You can make any 
subject simpler to teach just by making it wrong"?   ;^))
