And that's a very time consuming and somewhat risky operation on an old machine you want to keep running. Some old PCBs are quite fragile.

- mgsouth 2y agoYou can test ESR in-circuit, with caveats. Here's a good thread from EEVblog [1]. [1] https://www.eevblog.com/forum/beginners/is-there-any-way-to-test-capacitors-while-on-the-circuit-board/ https://www.eevblog.com/forum/beginners/is-there-any-way-to-...
