Otari MX-50 help

[MikeFFG]

Hey guys I just bought an old Otari Mx-50N off of a reputable ebayer, but it was sold as is so I knew it was a crapshoot buying it. It was too good of a deal to pass up either way though.. It definitely powers on and whatnot, but it is certainly going to need repairs as far as I can tell...I haven't officially tested it yet but the covering that covers the head, wires, etc is not with it, and it's hard to tell if all the important pieces at least are there. Does anyone have any good information on these? Any manual or schematic I could look at? I've found things on the later 5050's but the Otari website does not seem to keep up information on these. Thanks for any help you can give me!
