Some more food for thoughts....

If a copper shield is present in the coil it would be an equivalent to, roughly, 11pf capacitance.
296kHz resonance would then be possible with a 27.019 mH coil.
This translates to some 500 turns if the pot core in the picture is used.

OK, now we are getting somewhere...

As usual, the secret was rather simple.
Everyone assumed that the switch coil (collector of C1815) was a single coil. Am I right guys? [Oh, I am so fed up with cryptic messages from the authors that a simple answer would feel like a XMas present].

Anywayt, it appears that the coil is, in fact, three coils as in the drawn schematics.
I've managed to get some very encouraging results by re-winding the coil in accordance with recommendations by Melnichenko (attached).
I'll have to  re-design the circuit as I suspect there are some errors in it. A sort of a test for the replicators. It may work by getting the coils synchronize is a challenge. It also makes it very susceptible to voltage fluctuations.

I will perform a series of test with the new coils as soon as I reprogram my signal generator and write a scrip for Matlab. If the results I am getting now are confirmed by new upcoming experiments it would mean that much higher power can be harnessed that way. No more blinking LEDs.

Whoops...
Forgot the attachment. I am sure everyone has seen it...

I admit making this assumption based on the xformer gutting video.
