So lately I have been having a lot of problems with logic cards. So I decided to take all the IC's from a working one and put it in the one that was giving me the problems. Swapping all the IC's didn't fix the card. I put the IC chips from the non working card into a working card, and the card worked just fine. So for past experience, other than the IC chips, what is the major point of failure of these cards?

Which revision of card are you referring to?
Re-chipping these guys seldom works, I have had quite a few head scratching cards with faulty transistors on..
Andy can probably confirm that too 8)

I would have to look at the revisions. These are G series cards. One in a 1988 card the other a 1992 card.
On one I tracked it down to the not sending out the proper signal through a transistor. The other I can't figure out.
Do the transistors go bad?

yes they do ;)

from my experience e series logic cards rarely fail, but g cards certainly do, and it's usually a transistor failure.
try to avoid hot plugging channels, even when in a rush :) always had the feeling that's what kills them.
