Re: TC Inductance Formulas...

I've been trying to calculate the inductance of my TC primary. I have the
formula for a flat sprial and a solonoid, but I've wound my primary as a 30
degree inverted cone. Should I take sin(30) of the delta between the two
formulas? Is their a formula for inverted cones. I've not located a copy of
the Radiotron Handbook yet, It's on my get list.


p.s. Does any one know why usa-tesla is off the air?
