Hi Dan,

You have a very nice current monitor on Ebay (Item # 1924734436).  If you 
measure the ground lead current from the base of the secondary to ground, 
the top voltage is darn close to:

2 x pi x Fo x Lsec x Ibase = Vtop

Paul's programs could probably tell you the almost exact top voltage from 
that kind of data...

BTW - Your $50 price for that current monitor is 1/10th the new price even 
if it does get used once ;-))  I hope someone buys it before I have to 
:o))  The caps, filter, and variacs are also tempting me!!  I don't "need" 
them, but such bargins!!!

Cheers,

         Terry
