Bill,
As you know capacitors fail in many ways. Esr, I have found is the most
common. Occasionally I find a capacitor that has shorted. I Rarely find
one changed in value. Then Sencore has a dielectric absorption test. I
have only found one electrolytic in the last eight years that has tested
bad for D A. I find caps with esr practically daily.
A good ESR meter is a must!! Jay
