I recently aquired a solid state NST thats rated for 5K5V 27mA and 29KHz. Would this be really good for a small 'Coil? Would the design process be the same as for a traditional SSTC? I think that this would be great for a portable unit for demos and such.

Honestly that would work pretty badly with a TC. It probably has GFI protection, will die easy in TC use and the high frequency ac would suck at charging the cap.

Rectify it, it might work OK. But you won't get the resonant rise like with an iron core NST...

Like with flyback driven coils, first rectify then smooth, and use a small rotary gap, in your TC primary circuit. I have had fair results with small flyback driven coils with rotary gaps.

Naw, if I have to go through all that than I guess I wont build one with it. I really wanted a light weight device and rotarys are not light...

THIS I would like to see... cheesey I WAS planning on making a small RSG for my flyback driven SGTC but was "carried away" when I was hooked up to SSTC...

I would just rectify it, why smoothing it? Then you can use a static gap.
