Great, original Yamaha set of overall circuit diagrams for the CLP-240 CLP-240M CLP-240C models of electronic digital piano keyboard. This is the large overall circuit diagrams, all tucked into an original Yamaha service envelope with holes on one side of it for placing it into a binder if you wanted to do so. Very lightly used and in very good condition. The envelope shows some storage wear. These are original documents from Yamaha, printed in Japan, from 2005.
