I've made many a doorstop out of good NSTs that way! Just running the  GTO 
through grounded metal conduit is a real tranny killer, even in a neon sign.  To 
those running NSTs, keep your spark gaps set at about 1/4" or less to  keep 
the voltage rise from frying the tranny. NSTs are made to operate at only  
about 50% to 60% of their nameplate voltage, and even running one open circuit  
for too long can cause an internal arc to short out the  secondary.

Way to go Bert! That should generate a lot of  scientific interest in a group 
of people that don't usually fool around with  high voltage/high current. 
Congrats on the Edmond cover shot too. I've always  wanted one of your 
Lichtenburgs!

still very beautiful!  >>

Very glad to hear it's still going after so many years. Yes, I  still make 
plasma tubes of all kinds, but lack the skill needed to replicate the  old 
ornate Geisslers. You can take a look at some of my modern Geisslers on  
GlassArtists.org if you'd  like:

Hmmm,  care to make another trade?? Contact me off list if interested.
