I am a firm believer in John C's calculator! As some know, I've built
some very "unorthodox" tc configs and running even the strangest, being
the 3k coil, John C's calculator has always given me a good and reliable
spark length to expect!
My hat's off to Mr. Courture, I've slapped some very "unique" coils
through his program and by gum, it's been within a few inches with good
tuning.
Good work John!
Take care,
Marc M.
