Plasma Tweeter issues



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

Hi,  I assembled a plasma tweeter using an EL509 tube, and when I heated up 
the filament and connected the B+, I got nothing,  no noise, no 
corona.  The tube got warm, which is a sign of it working properly, but why 
isn't it oscillating?  Does the 100uh inductor really make a difference?  I 
am using a 120uH inductor.
