Successful test with k1zm-slayer007 toroid circuit.

Circuit will light two tubes in series, thus is putting out at least 1000 volts. Neon shows output is AC. Frequency is about 25 kHz.

   I had a question for you guys, but hard to put into words (green).  I am basically pondering all of the recent JT filament bulb circuits; and Marko's Filament Bulb Start+Run Cap Method in this video below has me thinking that his method (NO CAP CHARGING+SWITCHING NEONS/TRIAC/SIDAC) can be applied to all of these other BEEFY RESONANT curcuits:

  My thoughts are that putting bank of caps on L1 & L2 ( or L2+L3? ) would accomplish same results, capacity.  Any ideas or comments?

Ok I am on to something odd perhaps some of you big brain folks might be kind enough to explain this to me. Tonight in my home lab i was working on a simple SEC that was posted back 20 pages. It was using a trigger coil. I could not get it to work no matter how I ran the circuit. So I got upset and moved on to my JT test bench.

This is when things got odd. I know all about energy coupling and i think this is what is going on here but the odd issue is that if I hit a certain frequency power drops for a split second and BAM magic well magic to me at least. My theory is that I can run many cores and have then all generate power from but one source. And as I add them the amp draw gets lower and lower.

a few pics..

The LAMP is an LED light and its running from the JT.

I think you need to explain a bit more. Magic what?
