I remember a Grundig or Telefunken radio/phonograph which I think used a winding on the power transformer to give 110 volts to the phono motor...the power supply was adjustable between 100-240 volts so the proper power would be sent to the motor no matter what the input voltage was. The only problem might be 50 vs. 60 hz as the motor would run faster than normal if designed for 50 hz but I think there was something to compensate for that as well, maybe a removable motor shaft sleeve.
