Desoldered the old fuse. Found another busted part nearby, C201.
Tests as a dead short. Maybe that is what blew the fuse? Not certain why it would up a die by itself. The mains socket has a bit of filtering on it, so a nasty spike coming through the power transformer doesn't seem too likely, but I don't know enough about this area of electronics (mains inputs) to say for sure. Alternative explanation is that the cap was collateral damage of the fuse-blowing event, which from my limited knowledge seems less likely as no plausible over-voltage events are coming to mind quickly.
I'm gonna dig through my parts stash for a suitable replacement cap. To be continued...
