<< Hi All. I'm pretty late on the reply here, sorry.
 
 I saw the circuit at http://www.nuenergy-dot-org/plasmatron.htm in a 1997
 issue of Electronics Now magazine. I built the circuit several months
 ago, but replaced the SG3526 with a 555 (because I had those ; ) and
 a small N-channel MOSFET to invert. I left the push-pull stuff alone.
 
 I noticed no shoot-through condition. None at all. Even using a
 single oscillator and one transistor to invert....
 
 Needless to say, my circuit was a little unstable (555) but still
 performed okay.
 
 I wouldn't use the 555 for this. I would stick with one of the
 rock-solid PWM controller IC's. Like, for instance, the SG3526 ; )
 
 Take care,

Oh so it works?How about that 1mH choke?Is it all that important?
