Pretty sure that they are, and it seems all such radios used power transformers. 220VAC is a lot less forgiving than 120V, not that 120 doesn't deserve respect. After restoration, there's 240@60Hz waiting for this radio:
a power plug fed 240VAC (pair of 120VAC's) at my place. Turns out these old American crawfoot pattern outlets are the exact same shape and pattern as NZ and Aussie outlets.
The voltage being 10% higher shouldn't be much of an issue for the power transformer, as, for the same size transformer, it needs 5/6 as many turns on 60Hz vs 50Hz. So that 220V@50Hz transformer can accept up to 264V@60Hz. However, the filter cap voltage and heaters and so on may get a little too high, so a little extra series resistance may be needed.
