Dave:
I made a small Tesla coil with a 5KV, 5mA transformer and use it for
discharge tubes. Spark length is approx. 1.5 to 2". I used a two gap series
gap and two 0.0047? uF capacitors in series; #14 wire for primary and #26
magnet wire for a secondary (wrapped on 1.5" O.D., 6" long plastic pipe used
for toilets). Secondary discharge terminal was a 1" brass ball. I call it
my "junk box Tesla coil."
Also did experiments with a low pressure spark gap (glass tube enclosed spark
gap evacuated to approx. 100 mm Hg (100 torr) and found that a small Tesla
coil can oscillate when the input voltage is approx. 1KV. Secondary output
is weak, but it works for energizing discharge tubes.
I think you should give it a try, see what happens and take notes! Hope this
helped a little.
