piano disc

[Dean May]

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?
