You can run a 25 cycle set on 50/60Hz with no problems. The transformer is much larger and will actually run cooler than a 60 cycle one. The only possible issue is needing to increase the filter cap values slightly to get an equivalent reduction in hum.
25 cycle was common in southern Ontario and western NY right up to the 1950s in some spots.
