Rick...what did you mean by "on the east coast"? Just curious. 73, Jeff W3KL Jeffrey K.

The correct answer (at least for HP/Agilent CBTs) is that there is plenty of Cs in the tube, and they don't fail because they ran out of Cs. Something else will always wear out first. Regarding the general idea of rebuilding CBT's: a used CBT is so "cesiated" that it is not practical to rebuild it even on the regular CBT line. Even if it were, it is unlikely a time nut would have the necessary high vacuum equipment. It is pretty serious stuff. You also need to be able to laser weld the case together when you are finished. Sure seems like a "don't try this at home thing". We're still waiting to see if they can figure out how make 5071 CBT's on the east coast, let alone someone's garage.
