Oh, I got 50" sparks or better eventually. But I  could get better than that

with the same NST running 10nF  capacitance with a static gap on a smaller
coil with a much smaller  toroid and a "junk" setup. 
   But the SRSG wouldn't fire at all, no matter what  setting. I got things 
tuned to where it would fire, but only if it had an  initial breakout from
topload. Once the arc started growing smoothly, it  would sound great and
a nice long arc. But if the streamer extinguished, it  would have difficulty

starting over again. 
    I also had to disconnect the Terry Filter before it  would fire the
In fact the power resistors red hot and broke the enamel on  them after they

cooled. I also had to open the safety gap a little bit more than  safe to
it from firing.
    I know the SRSG is synchronous; it uses the typical  synchronous motor 
and I even checked it with two stroboscopes on two occasions  to verify the
BPS speed was synchronous and adjusting through the correct  range with John

Freau's phase controller circuit. The SRSG gaps were set very  tight; the 
electrodes would kiss as they passed if you breathed on them  funny.
    I also measured the coupling with the "suicide  cord" method (after the 
primary was tuned). I can't recall where it was, but it  was perfectly 
reasonable (around ~.15 or so).
    In some ways the same coil  acted similarly when run with the SISG and 
the Pig. The "wall  plug" ammeter sometimes pegged at 60A but with no sparks
the top. But once  it started to break out, it grew multiple streamers
