I know the inductors measure between 2.5H - 3H each. Have you tried hooking the chokes up differently? like field adding and field opposing?  I have the schematic and PCB layout on my website under "Media" > "Projects" so you can build the 8XA circuit just like I have. Dont worry about all the questions, thats what we are here for, right?

Right! thanks


The resistances you have an idea?

I'll have to double check but I think the chokes resistance was around 80 ohms.

Each?


Did you used two MOT's transformer as chokes? Or all in one?

ok, I just checked and the chokes measure 2.8H and are 40 ohms each.

Well nice, this make the time constant 0,07 seconds that would make a frequency of 14,28hz. Interesting is like if you could charge and charge before it gets discharged Maybe the resonance come from this.


Being the water also there the constant would become even lower.


I will keep thinking about that.



Thanks

I have a thought on the frequency doubling effect. From what I understand about Stan's LCL circuit is that the way the coils are configured is you get a positive voltage on one plate and a negative voltage on the other plate of the same amplitude. Now with these two opposite voltages and with this resonant signal that I'm getting, the two voltage will fill in the off time with a pulse. If I've got you confused just look at the image below and it should clear up the confusion.
Red signal is the positive voltage signal and Purple signal is the negative voltage signal.

There is a difference, though, comparing your drawing and the one Stan illustrated. Stan's signals are in phase while yours are 180 degrees out of phase. Stan's drawing shows the signals also do not cross the zero line or in other words, change polarity.
