Hello List, esp. Player Techs: I have for sale an early Model A Ampico mechanism for sale from a Knabe 5'8" grand. The expression mechanism with intensity adjusters and crescendo pneumatics for bass and treble are mounted as one unit along with a reservoir. The pump has metal connecting rods with cone type bearings. Secondary valves are upside down. Any interested person can e-mail me privately. Thanks, Randy Mangus,RPT
