Re: Sphere & Toroid Experements
Gary,
Interesting tests and results. One thing you didn't mention was if you
retuned (adjusted primary turns) for max spark length for each different
top load. If you didn't, then it would be interesting if you would run a
second series and carefully retune for each different load, then report the
results.

I know, I know, someone will ask what type of TC the test was done on.
