Plasma Tweeter



Original poster: "Jim Mitchell" <Wrenchead-at-starband-dot-net> 

Hi all,
Tomorrow I will attempt the infamous plasma tweeter, my question is, how 
does this thing work?  It has no primary and only an input voltage of a few 
hundred volts, yet maintains a plasma flame large enough to be heard at 
80dB!  Has anyone here built one of these, could it be done without tubes, 
or are tubes best suited for the job...?
