    Sounds like the next step is to slap on more Saran wrap and see if I can
rock it up a bit higher...

    Does this also suggest that a bigger topload is needed ?
    I ask because "on one hand" a larger torroid should decrease the Z seen
looking up from, say, 6" up the coil where the breakouts form, which should
(??) load the coil more.
     But "on the other hand" if the top voltage is a function of Cs/Cp then
a larger topload should decrease the available voltage...

    It sounds good on paper, but I always seem to get bit whenever I try to
maximimize any given parameter into the ground. Guess it's all a fine
balancing act...
