@TimeFlipper - a clarification question regarding the coil as it appears in your schematics: Am I correct in thinking that this is 4 pancake-like coils connected in series with air gap between them? And as you call this a Tesla coil, am I correct in thinking that this pancake coil is the coil designed by Tesla, Patent 512340 Jan 9 1894 (pictured here)?

No it is not a pancake coil...It is a cylindrical coil, similar to the one in the picture, but much thinner
