Oh wait, that's a different kind of buzz than I experienced in the above situation. Mine was more of a constant loud hum over the normal sound effects in the game.
That's the first thing I was thinking of when I saw the word buzzing. But like you mentioned the sound is a different sound than the wrong power supply.

I have used a few different top loaders over the years, but I know none of them made that sound. Or at least not at that noticeable of a level. Unfortunately, I don't have a top loader around right now to see if it is at the lower level that was also mentioned.
