Ok here is the setup. I have 2 12W 4" sheilded speakers in my cab (the ones from HAPP). I have a 10W stereo amp that I built from a kit from electronickits.com. The amp works fine, but I can hear the hard drives spin in my speakers, and a constant humming sound. I have tried moving the amp away from the power/computer but it didnt help. I have seen this before in car stereo installations and have solved with with a ground loop isolator. Do you think this is what I need to do in this case?? Thanks in advance! ED7 |

Better speaker wire? Shielded speaker wire? |

could be 60 cycle hum... is your florescent light on.lighting your marquee? is there a florescent light on overhead (try shutting those off and if the sound persists or not) if it is a ground loop the islationtf thing might work... shielding the wires couldn't hurt... you could also shield your circuit board too if it still won't go away... good luck... rampy |

Hey, Rampy, was that you I was fighting with on eBay today for that broken Star Wars yoke? --Chris |
| rampy:
you dirty rat! ;D yeah that was me... I had been watching the broken one and the more complete one as they were like 9 bucks and 15 bucks going into the last day... I was totally blown out of the water on the complete one (I tried to bid 20 something and it said sorry minimum bid 46.06 or something) Did you actually end up with it, or is that someone else that got it at the last minute. I'm not sure if I regret not bidding more or not, though... but not sure what good half a SW yoke would do me... rampy |
