I've heard that, and it makes me wonder if the reduced life is only as viewed
with the tube running at the reduced voltage. If you take a tube that has
reached end-of-life with a reduced heater voltage; I wonder if it would still
have a bunch of time left at the correct heater voltage.

I think this also depends on the tube.... as I recall it is much less of
an issue for power tubes than small signal tubes....
