   AG:
   I'm referring to what I was showing in my uploaded image, not the image that you posted. 
   My Kacher's HV signal is free flotting and not steady, as I'm triggering on the blue induction circuits signal. I can't trigger on both channels at the same time. With some exceptions, as I've shown.
In any case, don't worry about this.

Itsu:
I'm trying to make head or tails out of all this.
Is the yellow pattern the RF signal that you had mentioned? That signal is somewhat adjustable, although not easy to achieve that kind of sync.
But, more important is that there seams to be no extra gain at those points, that I can see. But, I'll look further into it.
As it does seam to be something worth checking out.

The yellow pattern is your Kacher output signal, as its frequency is 847.4Khz, its in the Radio Frequency region, so therfor i call it RF. 
It can be capacitively "adjusted" or "influenced" with nearby hand movement and / or ferrite rod inside the kacher tube. 

Not sure what you mean by "no extra gain at those points"

Can I use the TL494/TC4420/5200 transistor, to control that type of adjustable Kacher circuit?
As I have those components.

You can use your TL494 output (one or both) to tap off a signal from it (which obviously has the same freqeuncy as being used for your push pull (27.9 or in our
latest screenshot 15.3Khz)) and via some buffering turn on / off your 5200 Kacher transistor in sync with the push pull frequency.
Stalker, but also Oleg has presented some of those circuits in the past.

  Ok, so tapping off of the existing TL494 would cause the Kacher to run at the same frequency as the induction circuit. Some how that does not seam like what is needed. Now that you explained it to me.

   What I had in mind was to build a new board using the same type of TL494/TC4420 to fire the 5200 transistor at a controllable frequency. Can those two first components work at the right HV frequency?
500Khz to 2.7Mhz. Or not?  Also, would it be an "interuptor" or just a controllable circuit without any interuptor?

Nick,

with "tapping off of the existing TL494" i mean to use that same low push pull frequency (27.9Khz or so) to interrupt the kacher with, NOT to drive it with.
The kacher will keep on self oscillating at its own designed frequency (847Khz or whatever).

So you have the kacher running its own frequency (847 Khz), and you interrupt this self oscillating frequency  at the same frequency as the push pull frequency.
That way you get the bursts of RF kacher frequencies you showed in Stalker his screenshot.


The TC4420 is a MOSFET driver, so its designed to drive a MOSFET, not a transistor.
perhaps you can drive a transistor with a MOSFET driver, but it needs some adjustments i think, but its not recommended.
So you can change to a MOSFET to drive the kacher (google under SSTC (Solid State Tesla Coil) for circuits), then you can use the TC4420.

BUT...the TC4420 driver does NOT have an "Enable pin", so you cannot enable/disable (interrupt) the MOSFET kacher with that chip, so use a driver with a enable pin like
the ixdd604pi (this is a dual input/output driver chip by the way).

So to interrupt your present 5200 transistor, you can use the tl494/tc4420 combo you have now, but need an interrupter circuit for your transistor.

   Thanks again, Itsu.
   I'll look into finding an interuptor Kacher schematic. One that is the simplest.
   I like the kacher circuit that I just posted posted by Stalker. It looks simple enough.
