The grenade coil section in diagram contains errors and need to be corrected as per Ruslan videos in https://www.youtube.com/channel/UCacIIOzon1Us7mi4KkvJ3Sw/videos
Never follow blindly Russian diagrams For me it is natural as every single public circuit had to be corrected from day 1 of my experience in electronics.

Thanks again. So there is little chance that we are going to establish the correct grenade, Tesla coil & earth connections, given that most of us do not speak Russian and that Ruslan appears to be constantly altering his schematics and may not have found a self-running working solution himself.

Perhaps the https://youtu.be/QRhtLrNFRRY?t=10m10s will help with that?

I am reposting this piece of info. that I posted many months ago here on the thread....

C5 & R8 constitute an *all pass filter*.  I have built & used this same configuration with the 4046CD.

As stated on the attached diagram: Adjust R8 to *lag* voltage signal from output signal @ pin#4 to match (approx.) propagation delay generated by LM393/inverter combo.  This is probably less than a few hundered of ns.  ( I used the MAX942CPA and it's prop. delay = 80ns: FYI there are *much* faster comparators available)

take care, peace

Ok,  i guess T1000 was right, C5 should be 330pF.
With it i can shift delay the pin 4 output signal about 2us with the 5K pot (R8), with a 330nF cap there is no signal for much of the pot's area, only at an end it shows briefly a duty cycle changing pulse.

What frequency does the VCO suppose to run at with these value's?
With the R14 pot i can change the frequency between 3.3 to 8.5KHz, which seems rather low.
I have to adjust C2 to 6nF to get into the 15 KHz range.

No load (meaning yoke and kacher) attached, in fact, even the IR2184 and the UCC27321 are not installed yet.

  I'm at bit confused at the correct method to test the grenade coils for self resonance. As I don't see Akula, wrapping a couple of turns of wire around his test coil in the video, nor using a 50ohm resistor between the SG and the coil that he is showing the readings of. Did he forget to do so, otherwise why would he not show the set up using a 50ohm resistor, or wrapping the coil with two turns of wire?
  Any ways, here is my latest scope shot of the SG resonance testing of my grenade coil. Using a sine wave this time, but will do the same testing with the square wave later, using the 50ohm resistor.  I believe it to reads 5Mhz, but, that could be wrong.
Sorry that I'm so slow at the math bit, but I'm doing what I can.

Be careful when *shifting* the delay/phase too far when under load....... I have fried mosfets on my bridge doing that.

The Capture range will equal Lock range with typeII PLL , so one can set the VCO frequency range by using the desire value resistor on Pin#11 and the appropriate cap @ Pin#6&7.

The VCO will freewheel at the *lower* limit of it's frequency range with typeII PLL comp. so it could be normal.

Also, as per the Ruslan schematic:  Pot#14 (R14-pin#12) sets the VCO *OFFSET*, so this will shift the VCO frequency range 'UP or Down'.

So, apparently there is also a reason for a *variable* VCO OFFSET on this device also, usually just hardcoded with resistors.

Check the spec sheet if in doubt.

take care, peace

EDIT:  maybe wanted the variable VCO OFFSET so just one driver/logic unit could be used for a number of different device configurations.
