Hello All,

Does anyone know what frequency electronic neon transformers run at? 
I am looking at a very inexpensive 10KV 30ma unit. My thought was if 
the freq is up there it would be easy to add a voltage CW quadrupler 
for a capacitor charger. Thoughts? I would like to get up to 40KV. 
Higher frequencies allow for smaller value (and less expensive) HV 
multiplier caps. Has anyone experimented with these trannies?

Thanks,

   I think they run at something of the order of 50 kHz.  I have 
some stuff on my PC at work related to "electronic ballasts" for 
line-operated fluorescent lamps which discusses the nonlinear V-I 
curves for them and seemed to say that is an important factor in the 
design of the circuits.  Point is that I wonder if the "electronic 
NST's" will run with a load such as you suggest and, if so, what will 
happen.  If they're that inexpensive why don't you get one and report 
results?
Serious question.
