Why Does My Nottingham Motor Seem To Run Fast?


I just checked the speed of my Nottingham Spacedeck and at 33 1/3 rpm. the platter seems to move slightly too fast, that is, the hash marks on my gauge move very slowly in a clockwise direction. Should they not remain constant in place?

Ned, In your first post, you wrote, "Not impressed with the motor either, unless I spin it really fast it never gets up to full speed."  I am not sure what that meant, but I assume whatever the problem was, it has also been cured.  Keep in mind that the NAS turntables were deliberately designed to use a weak motor and a heavy platter.  The idea is that the motor only is there to get the platter up to speed whereupon it maintains speed mostly due to its rotational inertia.  The motor is only to give it a little oomph, once up to speed.  I no longer own a Notts tt, but when I did I found that a Walker Audio Precision Motor Controller was a major upgrade, like getting a whole new turntable up another level in SQ.
