Pardon my my interruption, but I have a suggestion to make.

Electrolytics can have health issues in at least two ways. One, mentioned, is that they lose capacitance from "drying out" and the equipment develops hum. The second issue that may occur is that internal leakage can increase, or even a short circuit develop. That may take out the rectifier and the power transformer if you are unlucky.

A more cautious approach would be to check the leakage current if you have the facility to measure it, or follow a more controlled reforming process. There are articles on-line on the subject of re-forming, for example:

I hope that is useful and interesting.
