I have four(4) of the cat# 4020SE Franceformers specified in the subject
contest. These are brand new transformers in good condition with a 120 VAC/60Hz
primary. I am selling them for $20 plus shipping to anyone interested. Please

I think that trying to have everyone measure the operating power of a coil, 
even just VA, particularly when using static gaps, will result in a lot of 
wrong measurements.  Terry's standard fuse suggestion overcomes the problem 
somewhat, but then the run time, off time, and fuse temperature becomes 
critical.  I like NST secondary VA - Isc times Voc, as anyone with a
multimeter
can measure it.

Gary, 

Yes, I did write the formula for true Watts originally.  Folks often quote it
as VA though.  VA could be used  for the competition since it would simply hurt
one's  results if they had a poor PF.  One still wonders what  quality of
voltmeter or ammeter may wind up being used in some instances.
