[time-nuts] 5065A Problem

[J. L. Trantham]

I have a 5065A that shows no PHOTO I or 2nd Harmonic.  I am suspicious that
the Rubidium tube is the problem.  There is voltage to the tube and I
measure no current from the tube directly.  All other indications seem
normal.  Does anyone have any experience trying to rejuvenate the Rubidium
tube from a 5065A?

Thanks,

Joe
