Bob, are there any URLs you can point to, or provide advice on, if
inspecting a Cesium for sale, is there an hour counter, or other metrics
that can be measured in the tube department ? (I am familiar with TWTs,
Klystrons etc so the HV doesnt bother me) in order to ascertain the
level of life left ?
that is, apart from turning it on and waiting a while and measuring ADEV
for a week.... on the sellers premises.

Based on several replacements on a “high performance” 5071 …. 6 to 7 years of

be about the point things start to get flakey. Maybe not dead, but crazy enough
that it lets you know
it needs a new tube ( = ADEV is not even close to what it should be ..).
Cost several years back for the swap out was right at $40K. The process
included hazmat shipping
silly nonsense. That part delayed the process by almost 2 months.
