Skori/Tefatronix/Teslaundmehr DRSSTC? 12-24VDC Test

Skori had initially made the very impressive small low voltage SSTC with what he said is a series resonant primary and this involved a rather loosely coupled twisted pair.
Tefatronix used a tighter coupled primary in sort of a flat-cable litz wire fashion and got rid of a majority of the components from Skori's circuit which were largely dealing with transients and trying to aid the interrupter switching. More power can be pushed from the secondary in this simplified version but it's not dual resonant unless the capacitance is intrinsic to the fets and layout or something. The second circuit I made following his SSTC IV schematic seems to drive my miniature coil a little better than my first build but I'm not sure why unless the GDT is simply more suitable.
Hadn't settled on a primary here so just testing in this video with ballpark calculations and grabbing capacitors I had laying around, but the output is still pretty nice with room for improvement.

In Teslaundmehr's drawing he proposes to just drive a series resonant primary on the circuit to see how the simplified Tefatronix version works as a small drsstc. I need to get more familiar with DRSSTC design because about all I know is the basic gist of needing to get the primary resonating at the same frequency the secondary is, or something thereabouts. What's crazy to me about the Skori driver is that the idea is to make some sacrifices in order to create a safe low voltage driver/controller combo that can throw cool sparks, but I've seen 120VAC coils out there which hardly perform better than Skori's 12-18V SSTCs unless they throw a voltage doubler in the mix.

At any rate I can see how appealing a ZVS feedback driven drsstc would be so that might be the direction I want to go. I want to be able to push long sparks from a drsstc while also comfortably being able to pull hot arcs from a continuous output but I don't want to invest a year and tons of money. If all else fails I think I'll try setting up my first half bridge with an adjustable primary and MMC and bootleg change the phase lead around when I want to go between CW and interrupted. I've seen basic SSTC boards out there with just an MMC thrown in and I mean hell it worked.. Guess you really don't need to go insane with the bus layout and spend a fortune unless you plan on contacting Thor directly.

Hey
great video !! also thank you for mentioning me;)
Your structure looks very good. The results are to be proud of. I think that this is a DRSSTC. Maybe a little more fine-tuning. I will also get started next week, let's see what's going on!

Great video, I think it is actually operating in a drsstc configuration because there is a LC circuit on not only the secondary but on the primary. For some reason I could never get this type of push pull circuit to work.

So how easy is to turn this into a DR setup? I mean i have the chokes and the res capacitor
