• Significant changes in room temperature - this affects the
viscosity of the oil in the bearing.
• Lack of oil in the bearing so check by adding oil.
• Changed belt tension or an oily belt or platter - clean
running surfaces.
• Turntable out of level – this affects the main bearing
friction.
• After adjusting the tension of the 3 small Philips screws
which hold the motor on, you may need to re-adjust the
speed as they affect motor bearing friction very slightly.
• Check the platter is not fouling on anything.
• A dirty bearing that exhibits too much friction - The
platter should drift round effortlessly with the slightest of nudges
( the lighter the touch the better) and go on spinning very slowly
before gradualy coming to a stop. If you suspect the bearing
friction to be a little high return the bearing to us for checking.
• A worn thrust bearing - this may occur after many years of
continuous use in common with all turntables.
• Transistors that have developed temperature instability.
• Most of the pulleys are a push fit on the motor shaft -
however they can sometimes work loose in transit or in use. If
this is the case then you can easily rectify it by lightly tapping
the pulley back onto the spindle with your fingers - Do not use
a hard object or excessive force as this can damage the spindle.

The motor needs a run in time of around 4 days continuous running.
They are sometimes a little noisy to start with so it is best to run in the
motor by continuously running it for 4 days on 33rpm. Do not run at
over 78rpm as this can harm the brushes over prolonged periods.
Most importantly you can “tune in” the motor to give minimum noise
by adjusting the tightness of the screws next to the motor pulley. The
best way to set their tension is to tighten the screws until they just nip
