"Don't turn up the volume. Turn down the world."
I just made one of the most significant upgrades to my audio gear. Yes... I disconnected my doorbell !!! I'm not joking. My late night listening sessions were always fraught with this underlying hum. :steam: Where is it coming from!? I looked everywhere. And, the hum seemed to come from everywhere; but, from nowhere. I put my ear to every component. I could hear the hum; but, it didn't seem to be coming from any of the components. Was it the refrigerator off in the kitchen; a light fixture?? Was the it the flippin' transformer outside!! It was getting pretty stupid. I was beginning to feel pretty stupid! :scratch: Then I looked up and lo and behold I saw it! It was the doorbell mounted to the wall. That's the source of the hum!!!!!!!! :doh: You've got to be kidding!!!
So, today I took the box off the wall. The electronic bell part came off pretty easily. BEHIND IT WAS A POWER TRANSFORMER LAYING UNATTACHED IN THE GANG BOX, HUMMING, RATTLING AROUND WHILE THE HUM WAS BEING AMPLIFIED BY THE HOLLOW WALL!!! To make matters worse, the transformer was on the same circuit that fed my audio gear!! Incredible. I'll have to post pictures later.
Now, needless to say, if you come by chez moi, be prepared to knock on the door.
