Older equipment should have power supply (and
elsewhere) electrolytic
capacitors tested/replaced as the average capacitor life span is only a
couple of thousand hours (2,000 hr). An ESR meter might help here...or
I really cn't beliueve it's that short. 2000 hours is less than 100 days.
Which, given a reaosnable usage period of the equipment (say 8 hours a
dayu on average) would suggest that on average an electrolytic capacitor
would need replacing after 1 year.
And that is not what I am seeing. Of course I've replaced electrolytics
in classic computgers. But I've certainly not replaced all of them. Many
of muy machines are over 30 years old, they have been used, and have had
no capacitors fail at all.
