Last year I installed a Dampp Chaser system in this piano as well. After tuning ,I turned on the piano disc and played a cd. When I was about two minutes into it I hit the stop button and started to pack up.</DIV> <DIV>A very noticable hum was heard comming from what I think was the amp.</DIV> <DIV>It was not there before. Also this piano gets very little use and was sitting dormant for at least six months.</DIV> <DIV>What can I do to fix it?</DIV> <DIV>Rick Ucci/Ucci Piano    </DIV></BLOCKQUOTE></BODY></HTML>
