No I havent as i'm only powering it directly from a SG. one of the probes is on the driver primary the two phases arnt on the transformer it self,  Any way you need to build it your self and develop your own power to drive as
loading a driver could well alter the phase shift. you could equaly make a CMOS circuit using 2 D types and an inverter to power drive
your out put stage, that way you would

I understood, thank you very much.

Thank you alan for your input, despite my sarcasm, I didn't at the time take into account what you were trying to get across. Now I am taking measurements configurations into account i think i see now what you were trying to educate me on. You are correct in the operation:
We want to drive our coils in resonance. This will occur when the frequency of the pulsed DC current matches the resonant frequency of the coils( And any other components in the system!), resulting in a larger amplitude of oscillation.

The pulses are to regauge the potential on the output coils, to make them "self-act" with one another during the off time.
Duty cycle plays a big role here as well. It can increase the coupling factor of the coils, as well as producing a big enough magnetic field. In Fighters ZPM, he uses 25% and probably has to because if its too low the coils may not reach resonance conditions at all. If too large, you are feeding from the source and/or wasting power you can saturate the core etc. and will cause resonance to become unstable.
This tells us also we need to pick our primary carefully, by having thicker wire we increase inductance per turn, also get a lot less resistance which is ideal for this situation. We need enough turns to have a good enough coupling with L2, though not so much that it will take too long to to get to max amplitude during the regauging  period.
AlienGrey: I didn't know ppl on this site were actually serious about replication. I may have that settup somewhere stored away and hopefully will have time to set back up. Thank you for your scope shots. I set the frequency that I intended to use, using don Smith's formula for the frequency needed to keep at cap voltage where I wanted to be for the output. Sorry I'm rly lazy and can't look this up for you but shouldn't be hard to find. The frequency I was running setup at was probably lower because of load and other conditions. But worked out well for the experiment. It's too late to say if this is a harmonic or exact relation to setup now that I took that apart the next day. Keep us posted of any progress.  I think my bulb may have been a 3.5W LED if that helps. It may also be worth swapping your primary coil connection along with your secondary to achieve better results.

And what, in this device, someone has achieved any success?
I tried this, it didn't work for me.

Please expand upon "I tried this, didn't work". Can you describe your configuration, core, wire length, awg, and turns?

Here a link to many persons who were a very big part of
This work ( for years)
And they share their findings ...(on topic tittle here )
Very skilled builders!

They might have better input and much more to say ..( person you mentioned "Fighter" runs or hosts the new Forum .
