FIX your Nintendo speaker "hum" or "buzz" sound - Now with video!
I'm currently restoring a DK and a Widebody Mario Bros. And as any Nintendo arcade game owner knows, these machines like to make a humming sound.
Since the amp is powered by the monitor, it picks up that interference and thus the speakers hum.
Some machines seem to hum louder than others. For example, my Widebody Mario Bros, hums louder than a pole-mounted transformer. While my DK, is much quieter.
Some people don't notice it, some find it charming, but it just drives me batty.
So I found a $10 amp on Amazon and hooked it up inside the machine. Thus, bypassing the original amp. The hookup is pretty self-explanatory but I believe I pulled power from the 7P portion of the power supply. I also just used long bread-board wires and plugged those directly into the PCB.
Bingo! No more buzz or "hum" sound.
And as an added benefit, I can mount it just inside the coin door and have easy access to volume control.
