John: Thanks for the information you are giving me. That goes for everyone.
This TC that gives 42" discharges, is this a 'regular TC' or something
different? Could I then expect something better than 10" sparks from my
3.25x10.5 secondary with a decent size toroid and say a 15kv -at- .06A NST?
Thanks, Dale.
