[time-nuts] repairing General Technology (Tracor) 304-B rubidiumstandard

[Bob Camp]

Hi

Of course, depending on the age of an Efratom lamp - it's also missing the
Teflon. I've certainly replaced enough of them. Since it's a combo gas lamp,
you can get away without all of the stuff in the 304 when you do the
replacement.

Stewart,

Tracor units use a high voltage pulse to start the lamp. You should be
able to hear the  relay that drives the pulse "clicking" around every 10
seconds or so until the lamp lights up.

Tracor lamp failures are  not rejuvinatable (is that really a word).
However I have in the past installed Efratom lamps into some 304D units.
