Let's see, will this make noise again? The original IC (TAS5342A) failed quite hard and burnt a few traces... (It's a D class power amp from a Marshall Stanmore speaker). Parts of the PSU died also (already fixed them). Not sure if the PMW controller before survived either (it does generate square signals on its PMW outputs, but couldn't see any width modulation).
