Hmm, okay, this means i have more work to do... i do not wish to accept 
needing staccato to achieve a spark length that other coils have done 
without the staccato.  Tomorrow i will disable the staccato and work from 
there.  Also, i know its hard to explain with words, but how red is 
'acceptable redness' ?  I have been letting the plate of my tube just 
noticably get a pinkish glow to it in the center of the plate.  At 30bps it 
becomes much more noticable, but perhaps im over estimating the level of 
redness.  I would like to have this coil running at 22" with no staccato 
and perhaps 24" with staccato... that to me would be an accomplishment for 
what ive done so far with my VTTC work ;)

Also, do your notes mention the parameters of your setup? mainly the tank 
cap as well as the level shifter capacitor?  Im using 2nf and 2uf 
respectively.  Oh, and how long could you run at 22" and 
non-staccato?  Just so i have something to go by.  Im sure i could push it 
for about 2 seconds before full redness sets in, but i have a feeling you 
were able to run it for awhile at that power.
