Re: [time-nuts] Are there any company selling refurbished/reconditioned Cesium tubes?
Taka thats exactly why in general we time nuts get the old sort of working equipment. We are on the tail end of life. Cesium tubes can not be refurbished economically as discussed many times on time nuts. Search the archives quite good reading. When a tube goes you have to find another system and save the old for spare parts for your newer unit. Sorry to say this. This is also why I do not run my cesiums all of the time. Just as needed.

Re: [time-nuts] Are there any company selling refurbished/reconditioned Cesium tubes?
Hi You will see used tubes for sale from time to time. That’s about the only “cheap” way to re-tube your dead Cs standard. It’s very much a gamble any time you buy one. There is no guarantee you are getting anything better than what you already have. There is nobody out there doing “real” rebuilding of Cs tubes. The market is too small and the investment way too large. They are very complex gizmos. Once they get to end of life they are pretty much entirely polluted with Cs all over everything. Cleaning, re-aligning, re-filling, and sealing up one would not be easy. Since the “entire world” of US Cs manufacturing has imploded into a single plant, it would also seem that there really isn’t a very big market for new Cs standards either ….. If there is somebody else out there making a whole bunch of them, they are hiding it pretty well. Bob > On Jun 28, 2019, at 12:12 PM, Taka Kamiya via time-nuts > wrote: > > I have a Datum FTS 4040A.

So, one "solution" might be to shut it down and start it up again? Haven't had this happen with my Z3801, yet, but guess I should expect it if I let it run long enough. ...

I have a Datum FTS 4040A. I believe the tube is original but it is still locking and staying in lock just fine. I don't know for how long. In an event where tube goes soft/dead, replacing it with factory new replacement part is out of question for cost.
