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.
I fully agree with Tony... replacing electrolytics just because of their
age is a very premature task. Today's SMPS and PC mainboards are another
story where you can literally see how the caps are failing (too much HF
stress and heat).
