ok, so i bought this deck cheap. replaced the power, RCA;s ground, the spindle needed replacement as well. so all that is fine and dandy, but, when i use it, i get an awefull hum, or buzz and there is only a tiny bit of music coming through. Iv'e don't all the usual, different channels, different needles headshells. even tried using different plugs. My friends techs work great on my setup. just this particular deck is giving me grief. Iv'e checked continuity from the wire jacks on the headshell to the ends of the RCAs, as well as all of them to ground. None of them are touching eachother, and none are shorted to ground.

do any of you have any experience with this? or have any of you happened to come across a troubleshooting guide? I've been searching everywhere with no luck at all.

its a technics 1200 mk2.
