Thanks for sharing. So i guess I don't know what my priorities are as I own both (an idler and a belt-driven table, just like many fellow wiredsatesmen I know) . I tend to agree with the observations though that 's why maybe consciously or unconsciuously, I am still keeping and happy with both.

*VERY IMPORTANT* AFAIK these were never imported to the USA. Make sure the pulley can be trimmed/changed (ala 301/401/TD124) for use in a 60hz environment unlike an EMT/Lenco.

The solution stated, in addition to changing the pulley to 60 hz, is to adjust/lower the motor's operating voltage.
I'll try to find where that discussion was.

Maybe you are right......FWIW, I added the caveat in a later edit for kabubi to think about if he is contemplating a purchase. As stated I don't know the Pierre Clement. Maybe it belongs to the category you are talking about?
I listed models I have hands on experience using/servicing (except the EMT, but trust Joel on this since he has serviced both 50hz and 60hz models of the 930) equipped with motors that can operate at both 50hz and 60hz with a pulley/trim change. I also noted the Lenco/EMT as exceptions because of the permanently attached pulley to the motor and will add Rek O Kut. ROKs are not much of a problem with a step down transformer because most of them were built/sold to a 60hz market......
Find and post the link that lists idler turntable models with motors that need to operate on a fixed frequency. This would be helpful and appreciated by idler enthusiasts.

JE- I had a chance to service the motor of my 930. The pulley IS part of the motor shaft- one piece! I am thankful its a 60hz motor!
