Hi

I have a tiny TC with the primary and secondary coil wound on the same 2" 
pvc pipe. Both coils are wound with #24 wire. The primary is wound 1/4" 
below the secondary with 5 turns of wire.  It is powered by one 10K 30 ma 
neon and the output is 12" sparks.  It has an RQ spark gap. The toroid is a 
brass door knob.
