Gary, Alex,

I didn't realize that you compared those two secondary sizes and
saw no difference in performance (or I forgot).  At first I thought
I saw no difference between my 4" and 6" secondaries either, but
now that I went back and re-tested, I'm seeing a difference for
whatever reason; 38" sparks vs. 42" sparks.  Very interesting.

To Alex:   Yes, a 4" by 13" toroid is probably too small for 
a 15/120 NST.  It will work, and give a nice head of sparks, but
you won't get the max spark length possible, esp if the toroid is
not smooth.
