Recently finished recapping my Data East sound board and power board in hopes to combat the hum/buzz many DE games have. This did not work, however, wiring in an aux power supply to power the sound board solved the issue.
Now, I still have a slight buzz from the transformer, but it is no longer filtering through the speakers. However, I still have a buzz during attract mode when the lights are dancing around (which i do not think there is a solution for yet), and I am also getting some noticeable "white noise" coming from the right speaker.
It is not a "hum" or a "buzz" but more like a white noise as if your not directly tuned into a radio station. I am not sure if this has always been there, and am just now noticing now that the main buzz noise is gone, or if this is a new issue.
Could this be a bad capacitor solder? I'm definitely not the best at it so its very possible...any other ideas what could cause this white noise?
Thanks,
Jim
