So has anyone solved the "Nintendo hum" yet?
I know for a fact that the problem is caused by the amplifier on the Sanyo monitor because I've fed the audio from my Super Punch-Out board directly into powered PC speakers, and it was perfectly clean; zero hum; but I don't know if it is an amplifier design problem or an interference problem resulting from the amplifier being mounted so close to the monitor and/or getting power from the monitor.
Replacing the capacitors and transistors on the Sanyo audio amplifier doesn't solve the problem ... ever.
Someone mentioned a couple of years ago that Mark Spaeth was looking into this. Did anything ever come of that?
It seems to me that a suitably clever person (not me) could design an audio amp that doesn't hum, and have it have the same dimensions/holes/connectors as the Sanyo amp so it would be a drop-in replacement. They could probably sell one (or two) to most people that own a Nintendo cabinet. People who I'd bet have the knowledge and means to do this include Clay Cowgill, Mark Spaeth, Jrok, and probably others.
