On my BII models dirty switches are usually the main cause of problems. Try cleaning the Speed switches, on front and the main board as well as the Reel (Large-Small) switch, exercise the Pitch Control knob(in and out) and Monitor switches. That H - L switch on the main board controls more than just speed and can be the fix for some of the weirdest combination of maladies. Had a machine that a tech said the capstan motor was defective. Cleaned the H - L switch and the capstan works fine. For that internal H-L switch you will need the main board swung down, then turn the machine on it's side, spray DeOxit into the side of the switch while working it.
