I believe I know that the answer is going to be "buy a replacement motor" but thought I would ask anyway. I have a nice 6300 that has been in storage for about 15 years in the original box. I dug it out yesterday and gave it a good cleaning as I wanted to check it out and set it up as a second turntable in my system for playing 45s and mono LPs. Once I had everything dusted off and reseated the platter, I noticed the platter moving up and down a bit as it spun when sighted along the edge. I removed the platter and spun the spindle by hand and it definitely has some wobble, almost as if it's bent slightly. I know nothing was ever dropped on this unit and I don't recall it having this issue when it was used years ago, but can't be sure. Is there any sort of adjustment for this in the motor or am I out of luck? Thanks!
