I had a customer, a piano teacher, complain about a buzz in an upright she used for in her class piano room and eventually found that an extension cord attached to a dampp-chaser was resting against the soundboard and would buzz only when 3 keys in the middle of the piano was played. I moved the cord off the bottom of the soundboard and that solved the problem. I showed her where the buzz originated. Good luck! Joy!
