Player Piano Motor Runs Backward
By John A. Tuttle

Hi All,  Here's a thought: The motor isn't running backwards. It's the
wrong motor.  Reminds me of a phrase: If it looks like a duck, and quacks
like a duck, it must be a duck.  The question is: What kind of a duck is
it?  Perhaps the old motor burned out and was replaced with one that
looked the same...

The correct Ampico motor is a Holtzer-Cabot ST-17, which turns clockwise.
The Duo-Art motor is a Holtzer-Cabot ST-16, which turns counter-clockwise.

 [ The ST-17 motor for Ampico is slightly smaller than the ST-16.

 [ We need data for 50 Hz 220-volt European versions.  -- Robbie
