I tried searching to see whether Power Sentry power strips have been recalled. I haven't seen any recalls. I seem to recall that I replaced this power strip once before (the previous one was the one that's in the front room on the floor next to the Papa-San chair which I use for laptop power AC adapters). Which makes me think that it's the stereo that's at fault, somehow. I guess I had had my previous stereo for about 11 years before I replaced it.
