yes...

The cell is actually a capacitor .. use this to calculate the frequency:  ω(0)=sqrt(1/(LC)-1/(RC)^2) you don't need that high inductance for your coils... better thing to do is calculate the resonant frequency of the circuit to a resonant frequency of water..  can you show what circuit did you use? About the water you must use distilled water for this to work consistently.

From my personal experience to date, the resonant frequency of water itself is not relavent.  Additionally, according to Stan, the quality of the water is not relevant.

no the resonant frequency of water is not relevent for paraller resonance.. meyer combined many things together from times to times , what is important for parallel resonance is water resistance..that's why I said to use distilled water.. because it has a fixed water resistance.

In my testing when I achieve Parallel Resonance, the water type doesn't matter because it seems the cell itself has no effect on the resonance. I know that may sound strange to some, but I can disconnect the cell and place a resistor in its place and still get the Parallel Resonance. The resonance seems to be taking place between the two coils!

What circuit do you use, I'm no engineer but you should calculate the capacitance of the water cell and the resistance of the water to make the whole system resonate in sync.. this way you could get over 50kV spikes on your oscilloscope.

I'm using the 8XA Circuit setup with my single tube.

Tony, I also get the same effect. Nothing really changes when I change the water or the size of the cell. What was the capacitance of the coils and the resonant frequency you found?

I found resonance around 2.5kHz using 2.8H and 3.4H coils wired out of phase.
