For information on the construction of neon signs see the following:


After the tubing is bent and the electrodes are in place, a high voltage and
high current is run through the tube while a vacuum pump is pumping the tube
down.  This heats the tube and drives out impurities.  A bombarment
transformer would be great for a tesla coil but I have not found any used
and the new ones are more expensive than a rebuilt distribution
transformer.  I had not heard of a bombardment transformer being built out
of old NSTs, but you could do it by connecting a number of them in parallel.
