Re: [TCML] poor preformance

[Gary Lau <glau1024@xxxxxxxxx>]

I agree with the cap size feedback, and the advice to not draw sparks to
the secondary.  Also, a secondary wound with 18 AWG will have a very low
inductance.  You really want to use a much finer gauge (#30-32) to get more
turns and a higher inductance.
