Several years ago I developed a class on disassembling the modern
Aeolian player pianos.  I have many photographs showing my method of
removing the upper player unit, numbering tubes, etc.  I taught this
class at two Piano Technicians Guild national conventions.  I believe
I still have CDs with all the photos and text.

Virtually all of these pianos need major piano service but never
receive it because of the difficulty in removing the player action.

Thank you.
