I bought EMT 927 several months ago and I finally managed to make it play. I had Hz problem because here the Hz is 60 and my EMT is 50 Hz version.
I solved the problem using Hz converter. The converter output is 100 V and 117 V only and I had to rewire to make the turntable for 100V.
Now it turns with proper speed. The sound is pretty good. Above all things, I could feel the sound played by the turntable was stable and neutral. This was very different feeling from what I had from Thorens 124 or Garrard 301.
Last night, while I was listening to the music, I found the speed is strange and saw the motor was shaking itself from time to time. It wasn't normal minor vibration of the motor which all the big motor has. Usually it turned quitely with small vibration which I think is normal. But it was sudden spasmodic trembling.
I switched off the turn and checked if any thing wrong with power connection but I couldn't find anything strange.
Has anybody experienced this kind problem? I cannot imagine what is going on with this turn
If you have any idea, please let me share your knowledge.
Another thing I want to ask.......
Since I got this turntable I read any information which is available on the net and found it might be DST version not usual ST. But I am not sure. Is there specific characteristic from which you can tell what is what?
