[time-nuts] SR620 - any gotchas buying a used one?

[Dr. David Kirkby (Kirkby Microwave Ltd)]

After regrettably selling my 5370B a few years ago, I decided to look for a
used SR620.

Are there any particular issues with these that could be tested by the
seller prior to shipping it? I have not downloaded the manual yet, but I
assume there's a basic test in there - probably similar to that in the
5370B manual.

Were these available with a Rb oscillator?  I see a seller on eBay that he
has some Rb ones for $1500 extra, but I don't see it as an option on the
SRS web site.
