[TCML] Running a Vacuum Tube as a spark gap or as a Relaxation Oscillator?
This is my first post. I have searched the previous posts but I have not found an answer to my question.
However the archives are significant in volume and it is possible I missed this question.
I have GU81M Vacuum Self Oscillating Pentodes. I would like them to discharge my 12pf Vacuum Capacitor when it reaches capacity.
I basically want to replace the spark gap with a Vacuum Tube.
I have seen circuits on the 'net that use Thyratrons in a Relaxation Oscillator circuit, but I do not how this is possible with a Vacuum Tube.
It may seem like I am being difficult but I have very good reasons for pursuing this. Namely that I want to reproduce the Tesla Coil design
as seen in Nikola Tesla's patents.
My conjecture is that you need nanosecond impulses of electricity to get this Tesla Coil operating correctly.
I have resistors and capacitors coming so it is no problem to give in and build an Armstrong Oscillator.
I do not yet have access to a power supply over 2kV as I live in a remote region of Australia (so a SGTC is impractical).
Any help, criticism, correction or tangential ideas are welcome.
