I'm having some difficulty measuring the inductance of my primary coil -
I
think because of old and crotchety test equipment, but maybe it's just
stupidity.  At any rate, I'm wondering - I have 13 turns of 1/4" copper
tubing on a 30 degree bank, spreading out from 6 inches to about 25
inches.
 Does anybody with a similarly-sized primary know its inductance?  (I am
just
trying to get a benchmark, to see where the problem might lie.)  
Thanks!!
