[R-390] Advice on Replacjng Components

[James A. (Andy) Moorer]

  Of course, I agree with all the good advice about understanding the 
problem first, knowing what you are doing, and being careful about 
rework in general. I would like to add one thing:

Every 60-year-old part you leave in the receiver is a time bomb waiting 
to fail. They weren't designed to last that long. If there is a choice 
between replacing the component or spending 15 more minutes testing it, 
just replace it. It will save you countless minutes re-finding it when 
it goes bad 10 years from now.

Just my humble opinion, of course.
