Better etching of the aluminum foil has allowed electrolytics to be smaller than they once were, but smaller size has resulted in a drop in ripple capability. There may be a low ESR in the size you n …

It would be best if you could test them with an LCR meter, but a shallow dent is probably not a problem. A bulge would be a whole diffent matter.

I don’t know how the Eico does the reforming, there are variations on the process. The typical way is to use a power supply set to the rated voltage of the capacitor, plus a resistor large enough to …

A problem with this circuit is that it is not transformer isolated and therefore dangerous. The 230 VAC line voltage just adds to this. Another problem is that capacitors used like this are prone to …

An aluminum electrolytic will handle a reverse polarity of about 1 volt or so. The cap probably never sees anything near that. This appnote from Nichicon shows that under 1V the capacitors don't h …
