I got a roll (on tape) of 22 uF, 10V and 47 uF, 10V tiny surface mount MLCCs. They’re not polarized, but I’ve heard they tend to be microphonic. I’m going to try leaving the old caps in and bridge a MLCC across them. They’re small enough to to go on the foil side of the PCB. If they work okay they should never dry out or need replacing. 👍👍
