OK Laurens, I hope you didn't think my remark was in any way flippant which was never my intention. You are certainly better ordering another 16uF capacitor instead of considering using a 10uF. Even with the wide tolerance found on electrolytics, 10uF is a little too low in value.

Yes, if components are visibly heat damaged and/or leaking then replacing them is a good idea even if they are not the cause of the fault you originally described.

That description sounds very much like a component(s) changing in value when they warm up.
