Hi Ken, Mark, and All,

This is my present idea for the cap life test do determine how long caps 
last run way over there AC voltage ratings:

Those little current transformers from DigiKey can monitor the current in 
each cap.  The transformer current and temperature, and the rail voltage 
are also monitored.  My second newest toy can track all the data and feed 
it to my old laptop (actually, my old laptop seems seriously dead tonight 
(memory/disk errors will not load OS anymore, battery gone...) :-p, so my 
new laptop...):

The 34970a is a super cool data logger!!  It can do just about everything 
and it has the 34401 multimeter's electronics to make the measurements. I 
got a practically new one (still in the original box) for about 1/3 the new 
price off E-bay!  I use them a lot at work, but now I have one of my own to 
use for "important" things ;-))


I also have now acquired the "full house" of 1:1 1:10 and 1:100 practically 
new Pearson current monitors (in stereo) after a few years on E-bay too ;-)).

So now you won't all have Terry bidding against you anymore ;o))


BTW - I have the new server online:

Once the DNS's propagate and the records "take", and "if" I didn't screw 
the DNS records all up ;-))  I hope to get the mail server going so folks 
on AOL and other ISP's that are having trouble getting list mail can use 
the mail server here.

Cheers,

	Terry
