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
4"
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
the
topload. Once the arc started growing smoothly, it would sound great and
make
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
SRSG.
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
keep
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
120
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
off
the top. But once it started to break out, it grew multiple streamers
loudly!
