One great thing about being a seasoned member of this fine 
brotherhood of high voltage pulsed engineers is, that if the recipe 
starts with:
"You take an OLTC", well then I can go to the shed and drag out an 
old battered prototype.
And when the recipe continues:
"Then sprinkle with SISG topping", then I have recent experience with that too.
Ok, Enough hand waving.
The guts of the product, the Off Line BRIck siSG Tesla Coil, can be seen here:

To get the gate of the CM600 open, I used a 36V TVZ, a 200nF cap a 
5Ohm Gate charging resistor and a 750ohm gate discharge resistor. The 
result can be seen here:

Resonant charging as usual,

Does it make sparks, oh yes! And this coil is one that appears to 
favour high break rates as seen on this short video, where I sweep 
from 63BPS to 1250BPS
