Now I know that capacitors tend to the component most likely to fail
on a piece of vintage equipment, but this is the first time I recall
seeing it claimed that lack of use accelerates deterioriation of
capacitors.
That is certainly true of wet-electrolyte aluminum-foil capacitors,
but they can be brought back by "reforming". However, ESR is a big
problem with newer equipment, causing heating of the contents of an
electrolytic and once those go, they're gone.
So you're damned if you don't and damned if you do.
All in all, I'd think that age is the big enemy, causing things to
dry out, plastics to crack and conductors to corrode.
