[time-nuts] Varian V-4700A Rubidium Standard

[Chris Quayle]

Found this on the usual site:

https://www.ebay.co.uk/itm/394869426524

Part of a collection of test gear found in a barn
by a house clearance company. Could not resist and
a 340 mile round trip to Cheshire to collect it. A
real two man lift, must be 80-100 lbs. Some
corrosion inside the open frame case and looks like
it needs an an external psu, but should be a great
restoration project.

Not much info on the web, but there is a paragraph
and more in the William J Riley "The History of the
Rubidium Standard". Turns out that this was one of
the first commercial examples of the type, from
around 1962. All solid state, other than a double
triode oscillator for the lamp exciter.

Has anyone here seen or used this type, and can a
manual be found for it ?. Serious historical interest
item and would be great to get it running and compare
against more modern types...
