Re: Design-and-building a large valve Tesla coil (class C, Armstrong oscillator).
Hey Dave,
Yes, me and Dave had a PM thread going for a while and I feel we both understand eachother a lot better and things are clear and easy now. Thanks for prompting us to be the best version of ourselves.
As I'm not working at the moment, still recovering, the project has taken on a greater significance for me than it would normally -my problem-solving capacities need exercising, like an enthusiastic border collie chasing endlessly after a ball! So my whole focus can sometimes go right down to this one thing... I expect others are familiar with this feeling?
All: more progress. I put a 10,000uF electrolytic right across the power supply pins to the MOSFET modulator -- far beefier decoupling. Performance is even more impressive than before. There is now 400V across the primary inductor at a supply voltage of 29V. There is noticeably less ringing in the waveform of the grid feedback winding.
