I've just moved (for the billionth time), and this is the first time I re-hook up my 12-year old Rega 2 turntable and find that it's running a tad too slow. I would like to know whether there's something specific that can be adjusted (i.e. a screw tightened) in order to normalize the speed on this particular model, as I'm thinking that perhaps the slowness can be attributed to it having been jostled during the 3000 mile move (it was working fine right before the move). Many thanks!
