Hi Tim,

I guess I should have documented what MOT I was using for scientific
accuracy ;-)  A picture of the label on my MOT that I used in my testing is at:

http://hot-streamer-dot-com/temp/P7220021.jpg

It says its a Toshiba 120V at 60Hz unit.  Model PX-532B.  Made July 24,
1983 if I read that right.

I weighed it at ~14 pounds.  Seems darn heavy and all.

"Not sure what it all means, but there it all is..."

Cheers,

	Terry
