Shashi,
You might want to have an electrician out to your house to help trace this and figure out what the problem is. You may have a poor wiring connection, i.e. corroded or oxidized contacts (acting as a semi-conductor or spark gap), that is causing 60Hz radiation as well as HF noise. Years ago, someone from Pepco knocked on my door to let me know that he was driving by with an RF monitor that they use (presumably for detecting power line issues), and was noticing excessive noise or sparking indicative of a bad wiring connection in my house. He explained that this is frequently a cause of electrical fires, so wanted to warn me. I suspect that your probe and speaker cable may be acting as an antenna picking up a similar issue. I could be wrong and it is unrelated, but having someone who knows what they are doing to help trace this down is probably a good thing.
