"Comment' is apparently limited - Twitter? Anyhow, you stated: "they all metered fine, maybe 5% lower than their rating,"Unless you have either ESR or DF capabilities and perferably a range of frequencies on your meter, you can't really assess a cap's condition.If you have freeze spray on hand, you can influence a bad cap by cooling it below ambient and waiting for the cap to cool for a few seconds.Electrolytics tend to go bad when exposed to high frequency components, including fast rise-times present in switched mode power supplies. Been dealing with this problem professionally for decades.If you find one decayed, you can lengthen its life by tacking a low-loss .22-.47 cap of equal voltage rating parallel to the electrolytic. It will then reduce exposure of the electrolytic to the damaging frequency.
