Let's try this again:
They are HP/Agilent/Keysight PN 10811-80008. I was actually able to buy
a couple from Agilent a few years ago. They are listed as obsolete

Hi
In all the years I’ve been doing this, there have been a *lot* of posts and
observations about that fuse failing. The number of reports / observations of
that fuse doing what it is supposed to do (protect a failed controller) have
been virtually zero. By far the easiest “replacement” is a
Hi
A lot depends on how good your OCXO is.
1) With a typical OCXO, the 1 second tau should be around 2x10^-11 against a
typical Rb. You are limited by the Rb.
2) With a good reference and OCXO the 1 second tau should be about 10X better
than that (2x10^-12).
3) With some OCXO’s you can do
Actually, in the unit in which the fuse had opened, it had protected the
unit when the thermistor failed open. Having seen this happen, I

Hi Chris,
Sorry for a delayed reply. The OSA 3210 is one of the only cesium standards I
don't have in the museum. I've seen one or two on eBay over the past decade
but not in worthwhile condition. I hope you can get yours working. If not, let
me know...
The good news is that I have an
