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?

Former Spacedeck owner here. Motor and arm are fine. The motor is a low torque design hence why you have to give it a shove. Supposedly it transmits less vibrations to the platter. The unipivot arm is normal, all unipivots do that.

Thanks Oz.
I am at a loss to understand why it plays fast though. It sounds great other than that. It will be due a bearing oil change but would think old oil would make it slow.... Unless it has been home fixed with the wrong oil. What a mystery.

Never heard of one running that fast.
Sure it has the correct pulley on the motor?
Very odd as mine was maybe 33.4.
I then added a Walker speed controller which is very popular mod in Notts decks and was able to tweak it to exact 33.33/4.
To be running at 36 something has to be seriously out of whack.

Hi

IE: bearing oil. From my understanding, the original developer of this TT hired a person Trained in that specific field  My friend Kevin @ K & K Audio owns a Nottingham. Apparently, their specific bearing oil has cat piss in it.

This is no S___.

Solved. 
Someone is receiving a belt and possibly some negative feedback. The belt is too fat to fit in the groove.
Just string has it turning at 33.3.
It can't be an official belt that I bought.
More to discover
