Hi, and welcome aboard.

The radio will work fine on 60Hz power.
As with all vintage radios, you probably want to replace all the waxed-paper and electrolytic capacitors before applying power.

The turntable however will be massively off speed (fast).

I would not even apply power to the turntable, lest the attempt cause some damage.
