Hi, I was wondering what you guys use for power supplies with your NES/Powerpak setup. I have slow lines in the video and a buzz in the audio...pretty sure it's because my power supply (Recoton universal) is rated at a low 350mA. Even worse when I have an electric heater running on the same circuit. Would I be ok with just getting the same supply with more amperage? Thanks.
I use the standard NES PSU, but since I've gotten an NES2FC adapter I've been using a 3rd party 9V 350mA PSU for my Famicom. The buzz seems to be caused by the PowerPak since it happens with no other cartridges. (If you have an expansion modded NES the buzz is even worse)

A larger power supply might help, 350mA is close to what the NES actually need and some power supplies tends to get noisy under heavy load. The original supply can deliver at least one amp.
Note that even if it works fine fine with other carts, it's likely that the powerpak demands more power due to the FPGA, CF card and other stuff inside it.
Just occurred to me, I've successfully used a One-Spot adapter (for guitar fx pedals) with a NES before, so I might try that. It can handle way more than 1 amp.
For added fun you can run your NES off of 8 AA batteries.

I don't think all the buzz can be eliminated unless the PPU itself has been disconnected. loopy made a replayer .NES for PowerPak for me a while back on NESdev forums that shut off the PPU when a button was pressed. It dampened a lot of the PPU humming, but it did not get rid of it. In fact the PPU humming can be turned into music. Blargg and I made demos supporting this.
