Piano Disk System 128

[Dave Bunch]

If the piano or player system has received no service since installation,
then this is probably the explanation for all the problems you describe,
although it is possible for an improper installation to cause immediate
regulation problems. Especially when you consider that player pianos usually
log more hours, they need more frequent maintenance than your standard home
piano. I'm surprised the customer is happy with the way the system plays. I
would be willing to bet that he would be surprised at how much better it
would play with some service and updating.
