Audio modulation by tl494 at the rails on the tefatronix sstc 28v with a small secondary the fets got hot too quick that is why I had to stop the video

Sort of the problem with this approach is that you have to tune the input power based on duty/freq for the best audio but you also can't turn it all the way up or nearly all the way up to hear it well. At least with mine I can't. So this basically means in order for me to get decent audio using that PWM circuit I need to already have a big enough plasma output without modulation that won't tune down to nothing once I try to adjust the duty. With this particular circuit you also need a fairly high coupling. I can get away with crazy loose coupling in the other circuit but not the Tefatronix one.
