Jonathon,
Thanks for your report. I agree that folks often set their safeties too
close when
using SRSG's. Provided the correct LTR cap value is used, the safety should
fire only if something goes wrong of if the coil is phased up wrongly. Once
the
phase is *close*, then the safeties can be widened a little. Most of the
problems
in the past with NST's going bad were probably due to such things as; 1)
erratic firing with static gaps or non-sync rotaries, 2) running with a
pure resonant
cap value. The safeties can be widened until the max spark length is
obtained,
at least that's how I run my coils.

Points for improvement have been noted, however. When adjusting the SRSG, I
keep getting longer and longer streamers, but then the safety gaps start
firing. I believe I have them set too conservatively far in. I think I
will open them up some. Also, my topload is 4" aluminum dryer duct around
standard-sized pie pans. I have some 6" aluminum flexible duct work (HVAC
style) that is more ridgid, and longer, so I can stretch it out around a
larger pizza-sized pie pan.
Glad to be playing with ~0.75MV again :-)
