To get 1Mhz5 you will need a good 1250 T on a 50mm drain pipe in the material world, pulsed or not to get it all in resonance or your pissing in the wind, like it or not .

Since you are all setup for this experiment, can you try grounding the base of the Tesla coil and adding various top loads to see if it's possible to bring the resonant frequency down by any considerable amount?

I'll try to do a similar test with my Slayer Exciter and compare notes with you.

  If you watch Andray Induction, his original Kacher coil was much longer, and he had to reduce it by about 1/2 to obtain the proper superposition frequency.  His spark, when touching any ground surface is quite strong. He's running on 24v.  That spark like Ruslan's spark is lot stronger than my spark, running at 12v.  And my Kacher secondary coil is quite a bit longer than his is, now, after he shortening his.
I will shorten mine as well, as I'm not hitting the proper frequencies, as it is. 
 
   Hoppy:  I want to try drive my Kacher on 24v. I'm currently running the base of the driver transistor with 2k ohms of resistance. What would that need to be raise to, in order to run the Kacher circuit driver at 24v.  Twice the resistance value, maybe?  Like 4k to 5K ohm, or so???
  I don't have any trim pots to adjust the voltage of the Kacher with right now. All the pots that I have have been previously burnt out. But, I do have some resistors, though.

Nick,

I never ran my Kacher at 24V, so cannot really advise you from an experience standpoint. A high voltage rated transistor is of course important, say 600V, 800V or 1200V working. The higher the C/E voltage rating, the lower the gain of the transistor is likely to be, so its really a case of trying various base resistance values until you are happy with operation with your particular coil design. T1000 may be more qualified to answer your question from a practical standpoint.

The Type-II setup here will lock on rising edges.  The feedback circuit shown is designed to magnify whatever signal is present on the current sense transformer (toroid).  It then clip the tops and bottoms off that signal with the two diodes, so it's no longer a sine wave anymore.  It then toggles between high and low at the zero crossing via the comparator.  In order for this type of feedback signal to work, you need considerable amperage on the sense wire and lots of turns on the pickup toroid.  The polarity of the current sense toroid is also critical.

Again, like I alluded to previously, this is a complicated device.  Understanding why Ruslan would want to phase lock at the zero crossing (either going high or going low--not sure which), is a bit of a mystery.

I put the above circuit together to do a little testing and noticed the minimum frequency is about 6kHz.  I think somewhere in the latest few videos he mentions the device operating at 15kHz, clearly lower than the 27kHz many thought was the sweet spot.  So we know he built a frequency range into the circuitry for a reason and it appears by adding/changing capacitors on the energy side of his device, better performance can be achieved.  This also gives me the feeling all the talk about wire length in the coils isn't absolutely correct.  It's probably more important that the ratios are good, but the frequency can be adjusted as needed using capacitors.  You may also notice in his latest videos, he has a large gob of capacitors all soldered together in the box with the yoke coil glued to the lid.

Also interesting is that he now uses instead of a single pulse to the Tesla coil, he uses a burst.  This can be easily achieved with a simple gate driver that has an enable (acting as an AND gate) and the Slayer Exciter circuit attached.  A word of caution though, you will need a heatsinked gate driver to run effectively in the MHz range and a separate (ternary) winding on the Tesla coil as the feedback.  That way you can still hard ground the base of the Tesla coil secondary as Ruslan stresses.

Now if only Ruslan himself would come on this thread and tell me I'm wrong and what I should do instead...

Good day Dog-One

Correct:  the feedback signal is basically an amplified and then clipped Sine Wave == Square Wave.

Also,  Could be that locking onto the zero X-ing with PLL enables a time base line/reference point for the synchronization pulse @ apex of Tesla sine wave.

take care, peace

  Didn't TomTech, or someone else, mention that on the latest Ruslan device video, that there is no PLL. Is this correct?

   Yes,  now all the caps are in the white box that's under the yoke coils.  All drivers are in the other white junction box. 

   TinselKoala:  I watched your video on the Mazilli circuit build.  Thanks for the additional information and details of the components you posted under the video.  Interesting. 
   Why don't you connect that Mazilli crt up to a grenade/yoke/Kacher set up, and join us here.
