The only tubz I ever got to produce a spark was a pair of 811A's which
produced a 3in brush (max) with the plaes over heating like crazy....What are
the speks of the system that one needs to use to get 11" out of them?..... I
also have currently, a 4-500z... which I have yet to get to produce
*anything* in the way of a spark (although it lights a neon tube up just fine
from a food away). Perhaps its my secondary and/or primary design... about
1000 turns of #30 on a 2in form (tall candlestick type) and a primary diam of
4" with 26 turns of #12 insulated house electrical wire (there are two of
these primary's, one is the real one and one is the "grid tickler" ) any
suggestions?
Thanks
