Or if you are ambitious, try replacing the motor bearings. Installation of a rheostat will decrease the motor noise and well as the volume at which the player operates. If there is a volume control already, turn it to a lower lower. I have not seen one of these pianos to know the specifics, so this is just general player knowledge. Depending on the age and usage of the player it may be time to replace the box entirely, it is simply a vacuum motor enclosed in a box and has a shorter life due to the restricted air flow causing it to run hotter than it's intended purpose (vacuum cleaner).
