Measurements
Hey,
I'm also building the don smith setup.
Currently I have done a couple of simple measurements from L2a and L2b coils with a pulser on the L1 coil.
Resonance lies around 43Mhz without any cap in the circuit, just pulsing the primair.
When I move the L1 I'm seeing spots where I can adjust the voltage on L2a and L2b. The scope shot shows the L1 in top position of L2a with 3V on the primair.
I'm currently simulating the L1 circuit ( Link ) in spice to see how a fixed freq NST would be used, you guys use sparkgaps but I wanted to see what the Surge Arrestor can do.
What I see is that it works to keep a max voltage and amperage going trough L1. Changing the SA value changes the max amps and limits the voltage to the SA value. The problem is the freq, my NST uses around 35Khz so with pulsed DC can it resonate on a harmonic of 35Khz 70Khz or for example 140Khz ?
What do you all think?
