Re: SSTC output looks more like SGTC output!

What is the power input? My guess is that the toroid voltage reaches the 
breakout voltage 5000 times per second, so its kind of like a SGTC with a 
really high break rate. What happens at lower power? I would imagine that 
the 5 khz would slow down, and that the toroid voltage would get a little 
higher because of the longer cooling time. I said that this might happen a 
few weeks ago, in the thread about spark length vs coupling, but I was 
hoping it would do the same thing for streamers. Is the toroid spunm, or a 
rough home made one?

I hope this isnt "old news", but i did something recently that might be of
interest for those of you who like to analyze things. Recently, i built a
full bridge for my SSTC (1.5KW). I was running it with a 4.5x15" winding
of 30awg and a small toroid (7x1.25"). This made the typical humming
hissing sparks that are ghostly yellow/white when you draw ground
sparks. Just about an hour ago :) i made another secondary. This one is
4.5x19" 30awg.
I tried putting a big toroid (5x16") on it. At only 30% input, the sparks
were loud, crackling, bright white streamers about 9" long! They only
appeared this way with ground strikes. The corona output (streamers only)
were still purple and looked like an SSTC. I could not crank up the juice
because of flasho! ver problems. But this makes me wonder if perhaps the
larger toroid is in fact charging up like a capacitor and then releasing
the energy in one bright SGTC like spark. The sparks also had a 5khz'ish
squeal to them. I wonder what would happen if i could run it up to 120V
input.
Maybe the thing would look just like a SGTC. It sure was loud like one.
Oh, and ozone production went sky high!!!

Another thing to note is the apperance of the RF envelope. When not
drawing sparks, it looked like a pretty much round blob (the common
look). But when pulling arcs, the blob turned into a series of very short,
but equal in amplitude blobs. Seems like each blob was an output spark,
and would explain the 5khz noise maybe.

Any thoughts? Maybe someone wants more information? Please let me know,
im kind of interested in this!
