Double post I guess, but...
You may well be getting some ground loop feedback from the TV. There are ways to correct this, but they're pretty involved. I'd say, try it quick with another TV perhaps and see what happens. If the buzz goes away, you know it's the TV, if not then you know it's the NES.

it's definitely the NES because it's there when i'm not using a TV at all. it's not there when i'm playing the NSF but it's unreal when i'm just on the menu pages of my powerpak.

Replacing the power supply may help. Talk to someone like Batsly Adams. He can steer you in the right direction.

As for this, I have considered that the RF adapter can induce a TON of noise into the works. There are also lots of old caps in there just waiting to fail/already failed. I'd still talk to Batsly, but eventually it would be very cool to be able to make a device which replaces the internal RF box entirely, adding a quiet DC-DC converter etc. Have you tried using a DC power adapter instead of the original AC? A new one?
