So… you own one of the rarest of all DX7IIs, the Centennial?!?

Then this original DX7II Centennial service manual is EXACTLY what you may have been looking for. It is complete, very detailed, with multiple page foldouts among the 59 pages plus the 7 page parts list, and includes the giant foldout overall circuit diagram.

It comes as pages tacked together (no cover) and 5-hole punched (which I believe is original).

Condition is good for its age, yellowing, creases, traces of storage, but no annotations.

Added to this is the October 1988 issue of Aftertouch, the official publication of the Yamaha users group, featuring the Centennial, in good condition.

Note that price includes s/h
