If things are labelled as 50/60Hz 120V, then running then with 
50 Hz should be perfectly OK (if it not OK then the device is mislabeled).
So with 120V 50/60Hz marked equipments you will only need 230V->120V
step-down tranformer to run them on 230V 50 Hz power.

Of the equipment is marked 120V 60Hz, connecting it to 120V 50Hz
can risk it's transformer being saturated and overheated.
