AC Synchronous Turntable Motors / Turntable Power Supplies
My turntable Motor Is Broken Down - Can I Get A Replacement?
To simply replace an AC synchronous motor with the same again is not as easy as installing our DC motor kit for the following reasons.
Simple AC synchronous replacement turntable motors are problematic as there are so many derivatives that it is difficult to specify the exact replacement - they all look roughly the same.
For an AC synchronous turntable motor one needs to also supply a pulley of exactly the right diameter and height as there is no other speed control. This in turn means that one needs to know the exact sub-platter diameter.
Even if it is possible to remove the pulley without wrecking it, there is then the problem of fitting it to the new motor shaft. Many motor pulley combinations are precision bored and press fitted which means that unless one is careful the turntable motor will be wrecked just by putting on the pulley - if pulleys are fastened on with a grub screw then it is likely to have a very slight "wobble" which is extremely detrimental to performance.
Many old decks can be given a huge leap in their performance by upgrading to our dc turntable motor kit - it is almost impossible to believe the level of improvement attainable until tried which is why we offer a money back guarantee.
Excessive Motor Noise
AC synchronous record deck motors usually run silently so motor noise is a sign of worn bushes and the motor will need to be replaced
