Hi guys,
I am going to pull it apart this weekend and do some more exploring. Hope to
get some pictures for reference.
I think I will make up some extender cables so I can operate the CBT
assembly away from the main chassis.

Your observations are tru for HP tubes but not FTS. I see FTS tubes after 2
years pump down in 20 minutes.

Tom,
On the 4060 you can easily monitor the Ion pump voltage and current, the
electron multiplier voltage, and other important parameters by measuring
the voltages on the U1 chip on the uP board.
This saves you fronm having to diconnect stuff to measure the HV and
such.
If you don't have a manual

Update.
I received the FTS 4060 unit and guess what - it does not work.
So a few questions to the experts on this list-
1) How can I verify that the CBT is in fact bad? Is there any easy way to
confirm the high voltage
).
Good luck.

hi
my 5370b is externally standardised by my tbolt.
the 4060 is locked, but is showing both alarm and align lites.
i am seeing 1 maybe 2 parts in 10**-9.
am i just looking at the tbolt moving around, or is it the 4060.
i think i will have to center the xtal oscillator.
new territory for me.
update: by centring the beam and control voltages, i got a lock.
i still have the align and alarm lites on. monitor lite off, lock on.
back to the book.

No the FTS 4060 does not use an HP 5061B tube (physically too big!)
However a 4060 tube can be used in a 5061A/B with a little work.

By any chance, does the FTS 4060 Cesium standard use an HP5061B beam tube?

No, wrong size (Corby, can you confirm?).
But it is not uncommon to see the reverse: FTS tubes retrofitted
into 5061 frames.

No, it does not. A new tube can be had from Symmetricom but you don't
want to know the price.
