You are correct, it is a modern amplifier and subwoofer/speaker set intended for use with a computer system. A few months ago, it developed a motorboating sound which I remedied by replacing a leaking electrolytic capacitor in it; it is full of cheap caps. It did not cause interference at our last place, so I'm fairly sure that lost another cap or two. I'll probably just replace them all this time around.
It's not how bad you mess up, it's how well you can recover.
