Poorman's HF Plasma Toroid

Well, this has been fun, especially cos no mosfets were harmed during the filming LOL, i found these FMH23N50ES that are ammmmmmmmmazing!! Anyways there are a lot of factors to mind, and changing even the supply voltage messes up things, in my case the tube i'm using changes the behavior of the oscillator a lot, and it's infact the plasma toroid that makes the oscillator work like this, i also need to hook up the scope on this but as long as not totally needed i'd avoid using my precious scope on "wild" circuits
