	IF, AND ONLY IF, YOU USE A SAFETY GAP WHICH WILL "JUST BREAK DOWN"
WITHOUT THE CAPACITOR.  Nothing kills an NST much quicker than using a
resonant or close-to-resonant capacitor and opening up the gap to get
bigger and better sparks; it works, but not for long!  Like a lot of
other guys here I learned that the hard way!
