Hi Jim,

I was going to post about using the "short the secondary" and measure
the primary inductance method, but using JUST hand tools;) requires
one to measure the primary current from the mains!  The local
electrical utility would not be happy.

	Your page is coming alone very nicely! When can I buy your
book? 

Unfortunately, varvom1.gif does not display legibly even in 1024 X 768
mode on a 19" monitor using netscape. I had to save the gif and then
look at it with _Graphics Workshop_ to see the schematic. Even then,
the "voltmeters" looked like they had a capital "S" in the symbol. 

note: all the other pics I looked at displayed correctly.

	regards,
