[time-nuts] Chances of 5061 and 5062 still having life in them?

I have suffered greatly from 'CS Addiction' since becoming a time-nut.  I
have purchased a total of 7 5061A's and 2 5061B's that were complete and 2
additional 5061A's for parts, one of which is missing only the tube and the
other missing various components including the tube.  I have been able to
get all 9 of the complete units working though one has a marginal beam

Their benefit is an independent primary reference and I have had an
absolutely great time learning about these units while getting them working.

As someone else said on the list, assume they will not work.  Then the
gratification of getting them working will be that much greater.

Good luck,

Hi Guys,
In Australia some Ce units have hit the surplus market.  looks like they
are from the 70s - that's 40 years old now.  What does the group think
the probability of the tubes having any Ce left in them and still
working?   Is it worth it now when one can use gps clocks to lock say an Rb?

Thanks for your thoughts
