I've been rotating the Burroughs 5092 tubes in my clocks yearly to even-out
the wear (sounds like car tires.....), but I'm inclined to do it less often

stressing the pins.
Has anyone done less-frequent rotations ?
Greg,
I don't understand why you'd ever do this. The digits of a standard
clock get cycled at least once a day by displaying the time. Poisoning
will only occur to cathodes that never get used. Who cares if they get
poisoned? They're never used!
I have had several clocks running in my house for over ten years, and
they work just fine. The only sign of age is silvering of the glass on
the ZM1010 clock, which doesn't interfere with the ability to read the
digits.
