Gentlemen:
 
Thanks to all for your fine suggestions. I was very close to simply
soldering capacitors in underneath the chassis on my T-4XC, but I tried
once more with the Weller soldering gun. I used a wire brush on the entire
tip (even where it attaches to the gun) and was able to desolder the tab
within a few seconds. 
 
I will let you know how this aspect of my project turns out. Thanks again
to all who responded. I appreciate all your responses.

Eric,

You indeed have discovered the problem, not enough heat. Both those devices
you tried were totally inadequate, not because of temperature, but of
extremely low thermal capacity. You might have to go to a 200-300 watt
soldering iron with a BIG tip and then you'll be ok; they have enough heat
capacity for just such jobs. As an alternate, but this is marginal, you
might try a propane torch BUT WAIT, what you do is heat the tip up to
temperature, then turn off the gas, and use it immediately to desolder the
tap with Solder-Wick. It may or may not work. The large soldering iron is
what works for me.

Work safe.

73s,

Evan
