Anthony,  I have a copy of a service manual printed by Aeolian a few
years back that describes complete adjustments and service type repairs
for Aeolian Player Pianos.  It was given to me by another member of
MMD, Don Teach who has a business in Shreveport, Louisiana.  I am very
grateful for Don Teach's generosity.

The manual was very helpful to me in providing me with enough
instruction to get the player piano back to complete working condition.
I believe the Aeolian Player Piano I own is also from the 1970 period.
The manual was difficult to understand at first, but with a bit of
effort I was able to figure it out.

I can make a copy of the one I have and mail it to you if you are
interested.  You can call me at (203) 762 8849  or e-mail me at
rocnos@aol.com.

Regards

Rocco Noschese
