Selfrunning cold electricity circuit from Dr.Stiffler

Hey gang,  to those that like to see waveforms and spectrum analysis of the Stiffler and
add to your knowledge, check my latest video of the Stiffler SEC.  Slowly but surely:

Well gang, there are 3 more Stiffler videos on YouTube that pretty well show how he does that 3 coil version.  My Hat's off to him for giving everyone this guidance.  Schematic, tips, really first rate information. Emphasis on isolation, position, etc. 

Only thing he doesn't mention but once is that it has to be excited to start it, then it runs, if that is the way I heard it.  I have everything to build it, test it, just have to wind 3, 22uH coils and match them at their approximately 25mhz self resonant frequency.  It appears that the better you match the three coils, the better it will work.  Then too, why not excite the 3 coil system with a SEC board operating in low power mode, feeding power back into the SEC via the AV Plug.  As voltage and power loops back to the power rails and increases, it should then click into high power mode if kept on the right frequency and you have the best of both worlds. Just thinking out loud.

Right ON,
Ben

I thought it was 26.62uH.   Can you confirm it is 22?

Depending on part placement, and local interaction,  it could be anywhere anywhere between 22 and 26+uH. Any idea what value of C he is using?  Assume in the 50-470 pf range.?? Placement and coil interaction is so
tied in to what is going on......The old 22uh ferrite that was used earlier has a self res. of about 25 mhz.  Wind too many turns and
then trim 1 turn or 1/2 turn at a time till you are dead on whatever X2 frequency you want to use.  Then match the other two the same
exact frequency as you can do with your test equipment.  Heck, I'm wandering around here in a fog anyway!

I have no idea.  It seems he switched to a new cap in one of his latest setup, along with that transistor.

I'm completely blind, but still try.
