Darn, that's a bit depressing.  I was really hoping your much improved test fixture (over Dally's) would show us the way.

So we're not back all the way to square one, but we are certainly missing something.  Any ideas as to what?

Don't be depressed or dissapointed guys, this was just a first test, lots of testing can/need to be done.
I measured the sine wave across the capacitor, not across the inductor itself (need to change the ground then), but will do that.
Also i could measure across the grenade output to see if that shows more of an disturbment.
I can also move the coax coil along the grenade/inductor, it now spans both, but it could try the inductor only, etc.

I count on you guys to continue testing with the kacher setup.

How did you synch it?
Is the phase shift between the sinewave and the nanopulse, smoothly adjustable between 0º and 90º in your circuit ?

I also connected the output of the TL494, which drives the push pull, via a switch (to select either TL494 output) to the input of the blue box which drives the nano-pulser IXDI414pi / IGBT.
The outputs of the TL494 is 15V, so i used a 1:3 voltage divider to input 5V into this blue box, see diagram below.
The blue box circuit can shift the input smoothly more then ±90° and also adjust the pulse width between 500 to 80ns (presently set to about 120ns for optimum nano-pulse amplitude).

Thanks T,

so that would be something like Alexee has drawn, only difference here is that the ground is NOT connected to the "under end of grenade"
(meaning from the 6th layer through the middle of the former), but connected to the 1st layer.

But the nanopulse can be seen over the 268V_P-P sinewave, which is weird by itself since the shorted coax forms a self-cancelling bifilar winding.  It is the worst kind of winding for transferring energy to another winding by transformer's induction.

My thought on this is we are attempting to recreate the infamous "coil short at peak" scenario,
but doing it in a non-direct manner, using induction.  Induction has three forms:  Magnetic,
Electric and a combination of both.

If we think about the wave traversing the coax, it's clear there is a voltage potential spanning
just a few centimeters, that moves from one end of the coax through the length of the coax at
approximately 2/3rds the speed of light.  We have to visualize this is physical terms--a high
potential on the inner conductor, surrounded by a low potential on the outer conductor, where
the outer conductor is in close proximity to the grenade coil windings.  By means of electrostatic
induction with insulation on the outer coax conductor, insulation on the inductor winding and
more insulation around the grenade coil inductor, we must be influencing the grenade coil.
My feeling is we just are not doing this in a carefully physically controlled way so the pulse
range (in centimeters) maps accurately from one surface to the other.  Rather, it is being
mapped in a somewhat chaotic fashion, where the chances of cancellation are exceedingly high.

I'd like to be wrong about this, but having attempted to physically engineer the exact
dimensions of these coils, wire thickness, insulation thickness, overlap, circumferences,
layers, etc,  this can quickly become a daunting task.  It would take a mind like that of
Tesla to visualize where things will be at certain instances of time and align everything
up with great precision.  And with all that riding on the premise we know exactly what
needs to be done.

Makes me wonder of the couple of devices we have seen running, how many coils have
been wound by these same people that simply do not work.  I would bet dozens and
dozens of them.  I suspect "close enough" is actually a very lofty goal.  We could be
talking about precision in the millimeters necessary to get all the wavefronts to align
properly.

I wish I knew a way to simplify things down to the bare concepts we could test and
validate.  There must be some engineering tricks that can be deployed to allow us to
keep the critical physical aspects accurate and repeatable.

I thought along these lines at the beginning of this thread. See here.

After few hours with changing coils connections and frustration I made call to akula and asked how he was tuning his version of device. It turned out he is using 28-30T yoke winding to power Tesla coil and the grenade coil output is going directly to the load. Also he is trying to get standing wave with reflection from the ground under end of grenade and the resonant harmonic frequencies are in range with electrons movement Larmor frequencies. Which makes electrons push for the gain in the output.
So here is general tuning direction...
Cheers!

Hi T-1000. Thanks for posting more info from Akula.
It is not clear to me however what Akula actually stated and what you
may have added onto that in your statement above. Did Akula specifically say that he thought
it was NMR or similar that was causing the OU effect, or what exactly did he say? If Akula stated he thinks 
it is an NMR effect causing the OU in this type of setup, when Akula is referring to this NMR or NMR-like effect,
does he think this effect is occurring in the copper wire in the grenade coil itself, or in the ferrite in the yoke
core, or in the copper windings on the yoke core, or where exactly dies he think this effect is occurring?

Also, have you asked Akula if he thinks Ruslan's various supposed self running device video demos are real or fake?
It might be helpful to know what Akula thinks about Ruslan's videos.
