Synchronous Motor Capacitor

[wingit]

I am new to this forum and electronics .. so please type slowly!

I have an old record deck (Systemdek) with a Phillips synchronous motor that is defunct and no longer manufactured. I know it is unserviceable as a multi meter shows open circuit between all three wires; the grey common feed and red and blue out. There is a very simple PCB that goes with the motor that consists of a power resistor, 6K8, to drop voltage to 110V from 220/240V for the motor and four capacitors. A friend lent me another multi meter which confirmed that the capacitors are as specified and I had already confirmed the resistor was fine. I can purchase a near identical (looking) motor from Farnell and few other sources all designed for turntable use and the same voltage and r.p.m .. BUT .. they specify a different capacitor capacitance from that which is on the present board. .

I will not pretend to understand how this works but there is a capacitor on the blue outlet wire of the motor. This makes it rotate clockwise (apparently). Here is my question .. the original motor has a capacity of 0.82 micro farads (400V) but the replacement motor I can find specifies 0.22 micro farads. If I buy the new motor and put it into the existing circuit to check that I've at least found the right solution to getting the table turning could I wreck the motor or would it just run less efficiently or perhaps at the wrong speed? I can change the existing capacitor before trying the motor however there was a hint in a spec. sheet I read that a higher capacitance can increase the motor torque (although perhaps cause more noise) and it may be that this is what the original manufacturers had intended.

Grateful for any help!
