Gary, All
The list of bad caps is on the list. Unless a lot of people have it on their
sites, most people wouldn't see it.

I totally disagree on you on the topic of depotted Jefferson's though. Ive
depotted two of them brefore. They weren't that bad at all. It was simple to
unpot. Just turn it over and put int on a pan. then stick it in my BBQ and
let it cook. the core falls out, i soak it in gas, then clean and its ready
for deshunting. This is the only pain for you have to cut them out. Its
easier now that i have good cutting tools. I believe two people on this list
have my depotted nsts which i gave away and last time i heard, both were
happy with their nst's and say they ran nicely.
