Nick,

with "the kacher circuit that I just posted posted by Stalker" you mean this below picture/circuit?

If so, then its probably similar as this Kacher drive circuit found here:
http://overunity.com/16674/sergey-alexeev-free-energy-gen-documentation/msg486646/#msg486646

I have picked out the kacher drive part and put it below.
You see on the left the K2511, which is a MOSFET followed by the HER308 diode etc. driving the kacher inductor on the bottom left.
Above the MOSFET you see the MOSFET driver (TC4451-UcC37321) etc.

So both this Sergey, or Alexeyka and Stalker are using already a MOSFET to drive the Kacher, not a transistor.

   Itsu:  Thanks again for the information.
   I may just go with the Stalker version, below. Unless you see some problems.

   The Stalker schematic is also taking from the existing TL494 circuit. Can it be used?
   Will the IRF260N mosfet work in place of their fet? Will it go up to the needed 2Mhz?
As I have plenty of those, in case of blow outs.
   Too bad the TC4420 driver won't do. As I have some of those also.

Complicated isn't it ! oh it's spread over on to an other board to, that should keep you bysy and off the streets a few weeks.

This one was done by Nnally it has a PCB too. But Mos Fet driver is crap and needs modifying.

Nick,

The Stalker screenshot you showed above does not show the Kacher (MOSFET or transistor) part, only the tapping off of the TL494 and some means to burst pulse
that tapped off signal (upper part), but i guess he uses the earlier mentioned MOSFET version.

I have not tried (or know someone who did) that specific circuit, so i don't know if or how it works.

The IRFP260N will probably work fine as a Kacher driver, just be aware of its 200V limit.

As both Stalker and others used the TC4420 MOSFET driver (without the "enable" pin) it can be used, only you have to "burst modulate" the input signal instead
of using the "enable" pin for that.   
Their circuits are designed to "burst modulate" the input using those TC4093BP chips you see on the diagram.


When googling for SSTC you probably find most designs will use a MOSFET driver chip with an "enable pin" to interrupt the kacher (Tesla coil).
So be aware there are 2 (probably more) different means to "modulate", or "burst pulse" or "interrupt" or whatever you want to call it the Kacher output.
