[R-390] Desoldering part 2

This terminal post is a bigger issue when the age of the modules are 
greater.

A '67 EAC is far less prone to this fragility.  The first run of the 
Collins built R-390As is an entirely different thing.  I found that I 
had to locate new terminal posts, as every one that I dealt with would 
fracture and then required replacement.

I found some on the Auction Place, and bought a pkg of 100.

I find I've become more and more like Tisha!  The less work and effort 
the better.

I want to do repair and restoration, not mental and physical abuse that 
is self inflicted.
