I've noticed a click through the speakers whenever my oil burner turned on or off; today I noticed it when a fan in the house was turned off. I live in a split level home- the burner is downstairs, almost certainly on its own circuit, the fan is upstairs. My system is on the main level, in the middle. I sincerely doubt they are all on the same circuit.
The offending click is low in volume, nothing that would damage anything. It is only noticeable when the volume is low, or nothing is playing but the stereo is turned on. At a normal or loud volume with music playing the click cannot be heard.
Any thoughts?
Thank you.
