    Hi to all, I'm building a big Tesla Coil, :) I want to see BIG SPARKS :). I saw that when I increase frequency sparks was brighter. So I was thinking in building a higher frequency PWM. I have 555 PWM circuit that can go up to 500KHz but I need more... Can anyone give me a suggestion on building higher frequency PWM, some MHz type :) like 10 MHz or something... Thank you.... You been helpful so far

    Yes I know :) I made one....
    But I saw that when increasing a frequency I get amazing effects... I can even transmit power wirelessly. I can make pulses with capacitors and spark gaps but i thought to make it a solid state.... I saw that max038 can go up to 20 Mhz but I can find it in my area... Do you now of some replacement?
