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.
