>From the answers to my question I realize this wasn't the simple question I
thought.  I was under the impression that this was a simple 1 foot = 250kV,
2 foot = 500kV, etc. type thing.  Silly me considering how non linear TCs
are. :-)

Being pretty new to coiling I realize I don't know much and the more I learn
about the principles of TCs it becomes more apparent the less I know.  Thank
goodness for this list and the vast knowledge it contains!
