I was closing down my HT a while ago, and I thought I heard a 60 cycle hum. It took a few occurances before I decided that I really was hearing it, it was that soft. It couldn't have been the equipment, since I could only hear it (barely) when everything was powered off. That was how it began.
Once I was sure I heard the sound, I couldn't help but hear it all the time...it became more and more annoying to me. Well, I looked high and low for the source. I cut all the breakers to the room, and I still heard the noise. I spent several nights wandering around the house, trying to pinpoint the source. It was driving me crazy. I was spending so much time with my ear to the walls and floors, my wife was getting jealous. Finally, the aha momement, the eureka discovery...buried in the basement ceiling, there is a transformer for the front door bell. It's screwed into an electrical box, which is nailed to a joist. When it hums, the whole house sings along. My first thought was to replace it. But the new one hums just as loud. I made sure every screw and nail was as tight as I could make it, but no joy. So here's the question: has anyone encountered a problem like this, and is there a simple solution, before I rip up the basement to relocate the electrical box?
