  I thought that I should test to see how many bulbs just the 3 turns coil/inductions crt can light, and to what degree. As I've never really seen it doing much of anything before. I'm running the bulbs at the 168 turns coil output, no rectifier, no yoke connection to that 168 turns coil from the yoke, either.
  Here's a picture of the 3 100w 110v bulbs lit. They actually look at bit brighter than in the image below.
  I can only manage this if using the magnetite magnet in the yoke, and ferrite pieces into the grenade former, to tune with. Otherwise, there is NO light without them. But, it's very touchy to maintain, and needs to be re-tuned after adding another bulb or two.
   I had a bit of added gain when previously connecting up the Kacher also, but not what it should do. And easy to lose that sync with the grenade, as well.
   Any ways, I'm still just tuning away...
   Anybody need any parts?  Ruslan's part store, (second image).  I wish that he'd sell me a couple of Oleg's driver boards.....
So, I could just connect them up, turns some trimpots, and there... Just like Ruslan is doing.

The first thought about this situation is about unbalanced forces. Seems your Tesla coil is having hard time to overcome the strength of magnetic field with the spike. The balancing of forces might a missing part in your setup.

  No doubt!
  That's why it would be soooooooo much easier if we had some ready made boards, to work with.  Otherwise it can take forever...

The blue is the driving square wave. The yellow is the coil output showing resonant LC frequency. In way the Tesla coil used I suggested to approach it from the point where you have Tesla coil as step up pulse transformer with top load as capacitor attached.
As you have problems with Tesla coil, I would like to ask few questions:
1) What voltage on the primary coil you provide?
2) What frequency your Tesla coil is resonating on with top load attached to the grenade coil?
3) What amplitude you get when driving with 1/4th wave length and with 1/2th compared to the full resonant wavelength?

thanks, but blue is "the driving square wave" for what? The Kacher (its MOSFET/Transistor)?

Yellow is the "coil output", but what coil? The kacher?
If so, it looks like  very low frequency, something like 300Khz or so (compared to the square wave frequency).


1) i drive the Kacher primary with 130V (but its a pulsed signal)
2) without ferrite in secondary it resonates at 1.38MHz
3) not sure what you mean, drive what? The kacher kind of selfresonates, i can not drive it with 1/4 or 1/2 wave length, i can only tune its selfresonance with the
ferrite rod in the secondary (lower it).

The blue is on the gate of driving MOSFET.
The coil output in the video was the transformer output. In Tesla coil case you will need scope probe nearby to pick up its signal(watch out for close distances, it can burn out the scope!)

3) not sure what you mean, drive what? The kacher kind of selfresonates, i can not drive it with 1/4 or 1/2 wave length, i can only tune its selfresonance with the
ferrite rod in the secondary (lower it).

So your Tesla coil resonates on 1.38MHz, the full duty cycle wavelength according to calculator in http://www.procato.com/calculator-wavelength-frequency/ is 217.24091159420288 meters and the time taking full cycle is 724.638ns (taken from http://www.sengpielaudio.com/calculator-period.htm )
The 1/4th of signal length would be 181.1595ns so the signal with duty cycle of that time would give you free oscillation on Tesla coil resonant frequency.
As the test involves forced pulse with which we want it bang on half cycle and cancel out on the other half the signal length of 362.319ns should enough.
