Here is my first good drsstc. Half-bridge of stgw30nc60wd (60A 600V), running at 127VAC Mains with doubler (~300VDC Bus) Primary Cap 50nF 1600V (I know it should be bigger voltage) I didnt make any protections so far, but I when I try the fullbridge design I will put some TVS and a Current protection.
Here are some pics: My H-Bridge (Wire-mess, but it works :D) and the sparks (~50cm to the air)
Interrupter runs from 50BPS to 600BPS (2,5A to 10A) Fres = 244kHz (Measured)

Here's my 6" coil. This coil was built over about three months, and it still isn't finished. I can't really go any further with it until I move out of this apartment. I can't test the coil easily for obvious reasons.
Secondary: 900T [25 inches] 22AWG on 6" form Topload: 7x30" + 7X24" Primary: 13T 1/4" Copper Tubing Tank Cap: 2X 50kV .025uF Maxwell Pulse Caps Transformer: 14.4 Pole pig [in the image below] Soon to be powered by a bombarder.
I've also built an 833C VTTC. I'm currently getting a maximum of 34" of spark out of the coil in stacatto mode.

(offtopic)finally managed to solve that e-mail stuff :)
My flower-pot SSTC, running 240vac from a variac. 30A H-bridge with a tricky optocoupler-based drive, the system is feedback-based and has an internal noise-rejecting interruptor triggered by external strobe from a remote control as well as any other strobe source. The secondary is 40cm high, painted with black spraypaint.
