Just remove the damaged caps. They are just local power supply decoupling caps to reduce power supply noise. If the noise you were hearing goes away then you'll know for sure that the caps are bad. It would still be a good idea to replace them but maybe not mandatory if it sounds OK.

I don't think its likely I did any major damage of course, especially given the state of the capacitor I screwed up, but I suppose damaging one of the TDA1543s isn't totally out of the question, but I don't think I could do that just by having a soldering iron in proximity for a few seconds... I have a ton of mostly useless old computer hardware, much of it from the P2 and P3 era. They are of course, covered in caps of varying values. The only high voltage caps I spotted though were some 4.7uf 50v ones. |
