Well of course this is a matter of personal preference, but if it was me I'd replace all of them.

Unlike wine, electrolytic caps defintely do *not* improve with age ;^)

Thanks to all who took the time to reply. Unless I find a cheaper
source for replacement multi-cans, I will probably gut the old can(s)
and stuff them with new cap's as Sam suggested. It is a fairly shallow
and crowded chassis, so adding parts underneath would be difficult.

Any comments regarding the need to replace based on the measured ESR
values? If not, I'll probably replace only the dead ones at first, and
see if here is any hum.

On 'lytics that have not seen voltage for many years, I know that I
should bring the voltage up slowly the first time. Should I expect the
ESR to change after the first few charging cycles?
