I believe I have all the parts to convert an regular upright player (simplex action) to a DUO ART player. I have a DUO-ART rotary pump and motor and, I believe, the complete expression parts. The only thing different, I think, I only have a Ampico tracker bar. Oh, I have the DUO-ART service manual Has anyone done this before ? -- Duaine Hechler Piano, Player Piano, Pump Organ Tuning, Servicing & Rebuilding Reed Organ Society Member Florissant, MO 63034 (314) 838-5587 dahechler at att.net www.hechlerpianoandorgan.com -- Home & Business user of Linux - 10 years
