Itsu:
   I should have tested the grenade output coil self resonance frequency, before I rewound the inductor to 48 turns and placed it on  top of it. But, I didn't think of it when I had the chance.
Now the 1 turns test coil connected from the SG, has to be placed on top of the inductor coil, which can influence the resonance readings of the output coil.
   So, in any case I'll see what the grenade reads with the new inductor in place.

  EDIT: Here's the scope shot of the new grenade readings. This is using a one turn coil over the inductor coil to test the grenade's output coil self resonance frequency.  I get 1.15 divitions, at .5us= 0.575us, for 1.74Mhz. Correct?

Why don't YOU guys do the PLL circuit and show how well it works (on the scope), when adding or removing 500w- 1000w bulbs.

  T-1000: That video is showing how the PLL works to maintain a steady frequency. Nice!  Yet, the bulbs still dim with each additional bulb, although the scope settings stay the same.  And for that device being the 4000w output version, ALL those bulbs look pretty dim, without the Kacher adding anything to the induction circuit. 
  Also, just look at his Kacher's primary and secondary coils in that circuit, using the long secondary, and a several turns primary (8 turns?).
  Although that is the not device version that I'm working towards at the moment, the question was: why don't you guys show what your PLL can do.  Not by showing how well Oleg's circuit works.
  I've already explained that I will keep my load of 3 100w bulbs steady, not changing it, for now. And tune my device to that load. And we'll see how steady the device works, or doesn't work, to hold the frequency.

I think he was referring to this schematic.

These orange windings are not really snubber windings because they do not convert the spike energy to heat but recover it back into the power supply, ...thus they rather deserve to be called "recovery windings".
