Is it common for the NES Toploader to make a "buzzing"/whirling sound when it is first turned on? I just noticed it with a Top Loader I picked up at the flea market today. Then I tried the Top Loader I've had for a while and I heard it when I turned that one on too, but it wasn't quite as pronounced. The sound rises up, dies down, then it starts again. When you play a game it isn't too noticeable. I tested both Top Loaders and one of my toasters with three different rf adapters, and the issue is definitely with the Top Loaders with one being worse than the other. I shot a short video to show the problem:
Would an AV mod fix this issue?
