Datum Efratom LPRO Rubidium Lamp removal

[Antonio Iovane]

Hi all,
does anybody out there have any experience in replacing the lamp on
an
LPRO rubidium oscillator?
I have two of these, one working and another which reads "lamp volt"
=
zero. I feel it is not a matter of lamp, as the lamp housing doesn't
heat (it should). I would try swapping the lamps between the two
units
for diagnosis, at least to know if I could rely on a spare lamp from
the faulty unit, but before attempting to loose the bolt which holds
the lamp into its housing I would like to know if this could damage
it.
By the way, does anybody have the schematics of LPRO?
Thanks,
Antonio I8IOV
