Sounds like I may need to rebuild the secondary. I am a little cramped for
space but if I made a modular secondary I could put on and take off, that
would work. Spacing is about a quarter inch or less, ID is ~6 so that is a
good guess.

Thanks for the tuning info.

 Specs
 NST 12kv/60ma 700 watts?
 Dunno the output. is 3' streamers max.
 Secondary is 3.95" OD with 19.5" of wound area of 28 guage magnet wire.
 Topload is 12" spun toroid.
 Primary of 11 turns, flat, tapped at ~10 turns.
 MMC .013uF
 Static air cooled.

Based on my calculations, this coil would tune properly when tapped at 13.3
turns.  A larger primary is needed if you stay with the present cap size.  I
had to make some assumptions about the primary design.  I assumed 5.8" I.D.
#10 wire spaced at .35".  This may not be exactly what you have but the
inductance doesn't change a whole lot by going to say .25" tubing or
changing
the I.D. or spacing a little.
