JVC tt-101 repair


Got a JVC QL-10 with a 120V TT-101. Speed is wonky. Sometimes plays fine, sometimes spins a 1000 RPM, somtimes runs forward & then backward. Could use some help.

 Is there any way to tighten up the rear couterweight shaft. Mine is drooping some.


the decoupling rubber is about to give way and must be replaced.

Watch this...


My arm’s grommet is not that bad. And I was afraid I might do more damage if I went further to try and dissemble it. I have a box of assorted rubber o-rings and found one just a little smaller in diameter than the grommet. I cut it and worked it into and around the front of the grommet to give it more support. Worked great, straightened out the shaft tube. Wish I could post a pic.
