[time-nuts] Heated crystal? & Rb tube corrosion (FE-5680A)

[Steve .]

Bill,

I was starting to think i may have to crack open an instrument to get a
picture. But i found a reference online.

Note the corrosion around the cheaper metal parts (screws, spacers, shell).
I can't speak for the FE-5680A, but when i see something like this in the
instruments i maintain it's a tale-tale sign gas mitigation.
