How old is the system? Some of the older systems did hum with the silver power supply.

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?
