symptoms of
degradation), we replaced them rather than deal with them
one by one as they failed. In our experience with our PDP-10 machines,
this was (despite its cost) cheap insurance against periodic failures,
which can occasionally be catastrophic.
That depends, a lot, on the PSU design. Certainly SMPSUs can do some
very odd things if a capacitor goes open-circuit or just high ESR. How
much damage that does to the rest of the PSU or worse the rest of the
machine depends on the design.
Do you think that the designers of this stuff have learned which approaches
they might want to stay away from? :-)
