Linn tabel won't stay on 45 slips to 33

When switching to 45 Linn recommends keeping the outer platter off, then turning the motor back on and letting the belt get set properly on the inner platter first, turn off, replace outer platter.

Also, cleaning the pulley with solvent-surgical spirits to help the belt remain in place.

New belt?

As I recall, before I got the Lingo with speed control, there was this flaky little adapter you put over the 33 rpm pulley that never worked very well for me. If this is still the case, I would remove it, clean with an alcohol wipe and reinstall. Best I can remember. The Naim forum could probably do a lot better. Good luck.
