Andy, you are correct when the item is assembled. However if you are restoring or repairing this type of set(and have it taken apart) it is very important to have the isolation transformer as the chassis (with its possible 120 volts) is fully exposed. In the case of the Hoffman and Motorola that I am working on, the entire metal chass can be hot-the line cord is not polarized.
Of course, when these sets are completely assembled with the correct knobs, etc, they are safe, unlike the 1940's radios that I have seen.
