SOURCE: Dual 1228 turntable platter not spinning, the motor will not turn

If the motor is not spinnig then it is probably seized. These motors are very robust and rarely need replacement parts. Remove both the top and bottom bearings, clean shaft and bearings with solvent and then fill bearings with light machine oil. The bearings have a sponge inside which will soak up lots of oil for years of trouble free use. Once reassembled, tap the bottom bearing while the motor is spinnig and the bearings will centre themselves. If the idler and it's mechanism is working ok as well then you should feel lots of torque from the from the platter when it is spinning.

Dual 1218 turntable


Does it say anywhere you can find that this turntable can run off 220V mains? Most are run directly from the AC and the motor is an induction motor meaning it needs a specific voltage and cycles per second to run properly. You may find that the manufacturer provided straps on the motor that can be unsoldered and changed to adapt to various voltage and ithat the speed can be altered via a speed control knob on the top to adapt to 50 or 60 cycles.

Runs fast about 78rpm.


You don't say if it's a belt or direct drive turntable. If it's a belt then something might have caused the belt to slip off it's normal position so it runs fast.
Direct drives are more complicated, but it would seem that the voltage control circuit that feeds the motor is applying to much to it and the therefore is faulty.

I have a sony ps-lx10 turntable, and want to connect it to a non-Sony system. The power ribbon needs to be modified. How do I do that?


First of all you would need to know 2 things. One the voltage supply needed to run the turntable. Two the voltage outputed by the non Sony system. If these don't match you could have a problem. For example if the Sony Turntable runs of say a 6 volt supply and the system puts out say 12 volts. You will damage the turntable. Chances are unless the non Sony system was actual made by Sony under a different name then the two supplys will not match. If you can connect up the two the Turntable will either run slow or fast. If the output supply is only 6 volts and the turntable motor works on 9 volts or higher you will never get it to run at the correct speed.
If you work out the two work off a similar voltage, you need only connect the plus wires together and the negative wires together and the motor should turn. Most turntables have speed presets, for each speed. You will need to find them and adjust them to get the speed right on each speed.

My turntable runs fast. At the 33 1/3 selection speed, it actually runs at 34 1/2. There must be a way to adjust that speed. Can you help? Tks, Tom


There are generally two ways the speed of a turntable is set. Firstly in the power supply section, you might find two presets one for 45 and one for 33. These are adjusted by placing a screwdriver in them. The other way is by presets in the bottom of the motor. This generally only applies to the 9 to 12 volt motor types used mostly on belt drive turntables.

1960s stereogram.bsr turntable turning to do fast.


If I can understand you right, the turntable is running fast. I don't think you need a new motor, generally the deck will run slow if the motor is knackered (or not at all). What you need to do is remove the platter, you will find a horseshoe bracket holding it on at the spindle (it may be covered up so you wil have to remove the cover part often a silver disc). The most likely cause will be the rubber idler tyre being worn damaged etc or out of place. There could be grease dirt or something else causing the problem.
