It's 2 octaves down, every octave is a harmonic of every other octave...

Mr.Fourier says that square wave has only odd harmonics and it does not have any subharmonics (no frequencies below the fundamental !).

Can you show a scopeshot of the currents in your Tr2 primaries across 0.1Ω current sensing resistors?
Ch1 between A and B
Ch2 between A and C

First without any loads on W3 and W4 secondaries and then a second scopeshot - with purely resistive load on W4.

Sure, I agree with that also, but then a square wave is composed of multiple frequencies, which will elicit the most response in the range of the toroids natural frequency using those harmonics that are the same as the toroid.  I had the same frequencies on other toroids and they did not audibly ring.


Yes I will try your suggested tests

Okay, had some issues... I had the real ground still connected to the circuit, so as soon as I connected the scope ground on the power side, it was a short to ground...started with the scope on each side of a resistor and doing a math function to diff them....


But, located the issue, and then able to connect with the scope probe inside the resistor from power (coil side) and the ground on the other side of the resistor  (only had a 1ohm high wattage ceramic cap, so it's 1, not 0.1).... it wasn't as clear connecting the probe the other direction.


This is 0.12A draw on the power supply...


So, where I am tuned, was not where I expected myself... I'm actually at near 0% duty cycle, using it as a sharp pulse up and down, and a high frequency to get the ringing in the L2 good... if I open the duty cycle too wide, it goes kinda staticy (ksshsrsh, how does static sound? )  instead of a pure tone on the toroid, and really stops working pretty much altogether, and draws a LOT of current, and doesn't really give me any better voltage on the neons.  So a very high frequency and very low duty cycles makes this a different sort of nanopulser... so being at 30-80Khz, I still get a great 9Khz tone


I haven't loaded the winding differently yet

Hi,

I need a helping hand. I'm sure there is a post about a high voltage measuring scope but I cannot find it. Could you please point me in the right direction?

Thank's in advance
