Hi Forum,
This is my first post. I put this is the Eric Dollard forum because it relates to impulse currents/electricity.
I don't know if Eric Dollard could answer this or maybe someone else can instead.
Preface:
I only have a high voltage supply from a microwave it has only 2kv and produces around 1kW. It can not be used for a spark gap. I however have GU 81m tubes capable of 750W.
I want to produce a 1kW Tesla Coil as Dollard described and as I have found on teslacollection.com.
I need a way to switch the current through the tubes when the voltage in my 12pf 25kv vacuum tube reaches the peak (2kV~).
What I want to know is this:
Is there a way to configure a vacuum tube to fire once the capacitor has charged so that I can use the tubes as a spark gap?
I have a Thyratron coming that I maybe able to use in a "relaxation oscillator" which will do the same. So maybe if we can create a vacuum tube relaxation oscillator using pentodes/tetrodes/triodes?
Maybe a voltage controlled oscillator would work but I have not been able to turn off my tubes once they to on (connecting grid to anode). I think this is cause by hysteresis.
Any help would be fantastic. I would prefer not to use resistors in my circuit.
Cheers!
BTW I am an amateur and have almost no training in electricity. I am experienced with high voltage and my heart still beats (not yet electrocuted).
