[HAM] 2 Questions

In order to remove the last oxygen atoms from the tube during manufacture 
they burn a material that binds the oxygen.  That process silvers up the 
inside of the tube, usually at the top but sometimes on one side ("getter 
flash").  Doesn't guarantee the tube is still good, but it isn't an 
indication of failure, either.  If the getter flash turns whitish inside it 
can be an indication that there is a leak in the tube letting some air back 
in.

De-Oxit removes corrosion on the socket side as well as the pin surface. 
Could be that the pin receivers in the socket have spread loose.  With 
caution, they can be retensioned.
