Thanks,
I have finally got around to completing the coil, I made a new half bridge from 2xIRFP460s The fRes is over 1Mhz afterall, about 1.5Mhz, due to the heavy gauge wire on the secondary.
I've made a video anyway, pictures coming soon. In the video the coil is running from 110V into the half bridge, and is half-wave rectified.

looks good
The streamers look alot like my vttc (probably becuase I used alost exactly the same secondary), although I am guessing that you are getting considerably higher efficiency... Mine was drawing about 15 amps

That's just adorable, Avalanche!
Always love the neatness/finished product of your coils - mine are never portable... they always remain as alligator clips and generally spread out over most of my desk =P

Thanks for the comments
Yeah I tend to spend a bit longer building things into complete finished articles now, my lash up projects from the past used to just get dismantled and I had nothing to show for all the time I spent
In the video I am running it from a fairly small 2:1 step down transformer, so it is current limited somewhat as well. Maybe running about 75 watts at a guess. I will be trying it on the 230v mains directly, but unfortunately this is the point at which my coils usually explode! Fortunately the MOSFETs are easy to replace, and I will probably drop some IGBTs in soon and add an interrupter/tank cap. That will be when I make my next order, until then it remains an SSTC.
A couple of recent pics, showing the new half bridge. This is how the coil is at the moment (note the sticker!) Last 2 pics - My new halfbridge design, and the secondary coil base.
