Got a problem with my mamiya, and need to open it up and have a good look. Sounds like a dodgy solenoid. Does anyone have a repair manual/ service manual? Or be able to point me in the right direction. Cant find anything..
Try Mike Butkus at butkus.org or orphan cameras.org. On his camera manual site under 2 1/4 Mamiya he lists Mamiya 645 repair. It says to write him regarding this ( 20 pages). I don't know if this covers Pro but would be worth trying to write to him I would think.
