I got this SL-B202, which I am really trying to bring back from dead. So far, I rebuilt the motor completely - now it's silent and holds speed accurately, and cleaned all speed control pots.
I tried to test it, and the arm would either slide off the record (when placed on the outer edge of a record), or would stay in one spot (when placed in the groove). This happens independent of the tracking weight (arm is balanced, tried with two different carts/headshells), or antiskate.
I checked under the arm - when set to 1.5g, the antiskate spring only really engages when the arm is approximately in the middle.
I tried increasing the tracking weight (up to 3g on AT95 cart), and antiskating (up to 4), but it doesn't make any difference.
The autoreturn mechanism was stuck, I just cleaned and oiled it, waiting for the oil to sip on all shafts, but I don't think that would Help anyway.
Thanks for your Help
I uploaded a short video to my google drive - let me know if this works please:https://photos.app.goo.gl/wkXKTxhXbewijgPA3
