I thought I'd slap a few rarely played 12"'s onto the lp12 yesterday, having not heard them for a year or two. Unfortunately my 45rpm adaptor doesn't seem to want to sit comfortably on the drive jobby anymore, and wobbles around making a bad rumbly noise. With the platter in place the wobble makes the bloomin armboard bounce up and down :mad: . Any tips? Do you think the adaptor is kapput?
