Yes, I've tried different cassettes, all act the same. I can see belts and pulleys/gears moving, but its likely the capstan or idler is not being engaaged. I am deciding whether to remove the front or not. I would rather not get in too deep. A previous service did get most of the hardened grease out of the mechanisms which did help. The REW and FF speed seem slow, which also points to the idler.
