[time-nuts] Efratom FRS lamp assembly repair

[VK3FGJM]

Hi All,
 
About 6 years ago, I purchased a bunch of surplus Efratom FRS Rubidium
oscillators running at 10MHz, wow what a finding. All 22 units did not
lock. I would like to share my findings with the group after repairing
them some time after.
 
My personal opinion is, Rubidium oscillators have a great long service
life, some maintenance is needed from time to time and it may depend on
the units mechanical construction. I have kept 2 units which I operate
and they are in fantastic working order. 18 years on they have given me
a great service life free from problems.
 
So don't junk your Rubidium oscillator yet.
