Hello, I have a toploader NES with an RCA connection at the back. When I use my plug converter (since I'm UK based) it plays the game fine, but there is this really noticeable buzzing sound. The converter info is: INPUT: 240V ~50Hz cos = 0.73 OUTPUT: AC 120V 45W Here's a video of the issue: http://www.youtube.com/watch?v=KqwPTEZLyzg&feature=plcp Anybody know if it's the converter? If so, what type should I get? Thanks.
