Several years ago I was walking around my house, when all of a sudden two people seemed to have a conversation in my music room. I grabbed a hideout, and went in. Nobody there, then they started talking again. It was coming from a Mission 707S speaker I had sitting on my main speakers. Just as clear as a real person speaking to me face to face. Listening to the conversation, I discovered it was the local police transmitting back and forth from base to cruiser. I looked outside, and there was a marked car sitting in the parking lot of a Pizza Hut across the street. The speaker wasn't hooked up to anything, except for the wire hanging down. I guess it was acting as an antenna. Freaked me out!
Never heard an amp do this before, ideas?
I have a primaluna 100 unplugged from any inputs. It has this awful high pitched sound coming from the speakers when it's turned on. It happens on both channels, and through headphones.
I have turned off all electricity in the apartment, turned all breakers off except the one it's on, moved the amp around the apartment, tried a humx, and different power cables. I even replaced the unit with another primaluna and they both do it.
I'm running out of ideas, anyone ever seen this before?
