It means that it may well not run at speed. Some motor design, rely on power frequency for setting the rotation speed.
But from what I read about the original motor of the L-O7D, it’s a DC motor which means there’s a controller upstream in the circuit doing the regulating . . . which itself may or may not be happy with any particular frequency.
That usually means a switching PS which could handle 110-240. Don’t use a transformer - a good one is going to be quite expensive. If it needs one, get a different turntable.
Yes, that’s technics top of the line turntable. The manufacturers website has all the information you need: Power Supply AC 110 - 240 V, 50 / 60 Hz
I would say worth shipping!
