[Boatanchors] (Boatanchors) 2013 Myth

[Jim Wilhite]

Another clue I have seen is when you find one or more split from end to end 
or cracked.

That is what led me to looking and testing according the the manual with my 
TO-6. If it meets the resistance check, then fine, if not it is replaced 
and I check them all. Most BB caps I have run through all show very low 
resistance so I replace them.

The trouble with them seems to be centered around heat, they don't seem to 
be able to take much if the air flow in the equipment is not adequate. Use 
them at your own risk.
