[time-nuts] Repair for HP 5071A Cesium Clock

[Bob kb8tq]

Hi

The usual “best guess” is that the tube has reached end of life. The answer is to send it back
to Beverly MA. They will replace the tube and re-adjust the device to work with that tube.  The
process involves getting a “shipping kit” from them. The device goes back in that box and does
so as hazmat via FedEx. Entering a package like that into the FedEx system involves a person
with special training doing the entry. (At least that was the case when I last sent one back). 
Needless to say it’s a hassle. 

Cost typically has been 40 to 50% of the price of a new device. It was ~40K a decade ago. If
the “new price” is now $95K, it may well be up to around $50K by now. 

Needless to say, that’s a lot ….
