Most European countries have 220 volt, 50-hertz electric power. You can use a transformer to step the voltage down to 110-120 volt for use with American electronics, but the difference in the cycle rate is a problem for motor-driven equipment such as turntables (the lower cycle rate makes the turntable motor revolve more slowly than 60-hertz). Sometimes the turntable motor can be modified for the 50-hertz current, and sometimes it can be adapted to 50-cycle by the use of a different size pulley. Perhaps some of our European members (Ben Campbell, are you online?) can comment in more detail.
