Hi, just inherited an old (I think it's 1980s) Technics sx-k200 in what seems to be perfect condition (except the pedal is missing), and am wondering if anyone knows where I can get an owner's manual? Would it even be worth the time to go around looking for one, since the only thing that's not obvious is how to use the cartridge. Or does it have hidden powers and capabilities I'm not aware of? I'm not really an electronics keyboard guy.
