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

Tim

I would guess it revolves around the cost.
Impossible to say if any CS is left. But for cheap it may be worth trying.
But then shipping will most likely get you.
I do agree GPS locked RB is a very nice way to go. At least in the US
various RB references much newer in age with possibly more life show up on
epay all the time.
I have an older hp5065 RB that still working like a champ those must be at
least 30 years.
Good luck

Hi

It's quite possible that they have been re-tubed three or four times
already. That makes the estimation process pretty tough.

Pay for them as if they were dead, feel good if you get a working one. Don't
feel bad if you get out-bid...

There are indeed things that a Cs can do that a GPS locked Rb can not.
Running a Cs 24 hours a day 365 days a year for years and years can be
pretty expensive. A lot depends on what you want (or need) to do with it.

Bob

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
current.

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,

Joe
