I'm trying to get information on a recently purchased player piano manufactured in 1979. The piano is a Baldwin. The conversion appears to have been done by a company called "Music Box Productions" in Irwindale, California. I have been unable to locate any information about that company. The conversion kit has a circuit board with a transformer and five relays mounted to it. It also has two solenoids that appear to operate the play and rewind function. It has a conventional five-section air motor. I would appreciate any information. I can furnish more pictures if needed. Regards, Richard O.
