Ampico A Pump Regulation
By Bruce Clark

Have any of you noticed that the pump vacuum of an Ampico "A"
changes as the tempo is increased?

I have been adjusting my Ampico to 30" while tempo is set at 65.
However, when the tempo is set at 90, the top setting of 30" is
lowered due to consumption of vacuum by the air motor.

I would like to hear from others who have noticed this.
