A Whaxor is a tired Haxor isn't it? Hey I'm sure even the L33T among us 
have a  sense of humor.

Mmmmm. This makes all too much sense. It also sounds like some rather 
dedicated aparatus would be required. It would probably be a pretty sexy 
device as far as devices go but it would require me to build something. 
(Other than what already may, or may not be on the cards.

But this also begs the question. Wouldn't this mean that you could only 
pump one cap at a time? The guy I knew doing this use to do it in banks. 
Maybe 20 or so big caps at a time. But to do it absolutely properly you'd 
have to measure each cap's "performance" individually? Otherwise a bank of 
caps would read some kind of exponentiated average wouldn't it?

I am of course in "I have no clue what I'm talking about." Mode at this 
point. But it seems reasonable that no two capacitors would have the same 
finger print.

Anyway. Thanks for that. Looks like I'll be fudging and hoping for the best 
for a while longer.

Be absolutely Icebox.
