Have two issues with this turntable
1) When started, the tonearm goes all the way to the center of the platter. There is a set down adjustment "screw" by the tonearm base (actually a metal plate with a screwdriver groove cut into it) but movement of this plate in any direction has zero effect - tonearm always goes to the center. I'm familiar with Duals and grease drying up causes a variety of problems, but haven't work on any technics internals. Is this is a similar issue where some part might be sticking or not releasing properly,m thus continuing to carry the tonearm across the platter? Anyone seen this issue before?
2) The counterweight spins completely loosely (e.g not on any groove). I found a small piece of plastic to be floating loose up inside the tonearm and with a shake it fell out. It appear to have the necessary "lip" on it to catch the groove of the counterweight. I might be able to superglue this back together IF I could find a way to get the back half of that tonearm off. But I can't figure it out. No screwdriver or hex wrench instead into to the back end seems to catch anything that would unscrew this piece. Even if super glue wouldn't hold, I still need to get that piece off to replace it - If there is even a replacement part available? Any ideas of how to remove this back half of tonearm when the counter weight sits and where a replacement part can be sourced?
