Maybe turn the plug around in the wall socket (if it's not polarized)? --Cy-- ----- Original Message ----- From: richard.ucci at att.net To: pianotech at ptg.org Sent: Monday, January 08, 2007 5:56 PM Subject: piano disc Hi List, Tuned a PR gp-142 with a piano disc system today. 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. A very noticable hum was heard comming from what I think was the amp. It was not there before. Also this piano gets very little use and was sitting dormant for at least six months. What can I do to fix it?
