I really do appreciate your help!!!
The only thing I notice is that this circuit is different from the one you used before.
The one you posted is just the same as the one I posted before.

Slightly different from 5 to 6 pins for transformer.

  I'm sorry it didn't work. That is the highest turns ratio transformer (readily available) that I know of. But it looks like an even higher turns ratio is needed. My F4T5 tube measures about 96 volts when lit. So you might try 3 volts just to see if that will light your tube, but the transistor will get very hot at 3 volts.  I hope your next project works better.

Wow, my dump never has anything that cool in it. Maybe one day......

@ Freezer:

Man, I am impressed!  Lighting a CFL and a neon off a single AA!  Good light level to from what I can see.  Again, I have to say that you do very neat and organized work.  Excellent job.

My guess at Freezer circuit.
