Radio friends,

I'm working on an interesting Italian console radio/phono.  The unit appears to be a combination of a Vertola radio (modified, perhaps homebrew) and a Contina turntable identical to that shown for this model.

The instruction page (viewable here on the Primafon model page) mentions that the turntable has an induction motor with selectable voltage ranges 110-120, 140-160, and 210-220 VAC.  It also indicates 40-60 Hz, selectable ("40-60 Hz umshcaltbar").

I have found a typical "wheel" type voltage selector on the unit, but I'm having trouble understanding how the AC line frequency could be adjustable.  Induction motors tend to run at a single speed tied to the line frequency, and this one appears to be no different.

Does anyone know what they meant by "40-60 Hz umchaltbar"?  Is there in fact a way to make this run the correct speed on 60 Hz?

As it currently stands, it runs too fast, as one would expect when running a turntable designed for 50 Hz on a 60 Hz line.

On a related note, does anyone know of a source for replacement rubber tires for the idler and turret on this turntable?  The originals are still working to some extent, but new rubber would be much better.

Thanks,

Tom
