I did a bit of experimenting, I removed the belt,
the noise only occurs when the motor is on and the needle is either
in the groove, or outside the groove and not moving tangentially/skating.



Presumably you have removed the transit screws from the motor.....????

Yup. Forgot to mention that. Yup. These have already been removed and
the motor is hanging freely on its elastic bands.

Its either electrical or somehow vibration is travelling through the
tonearm, as it was still audible when the record was lifted clear of the
platter.

Hmmm,

Apart from two other chaps mentioning hum on avforums (One who may not
have earthed properly). It looks like this could be something more
widespread..

But this could be a red herring on my part...
