Silvertone, or probably Colonial radio under contract, must have used the type #45s as a cost saving measure and as a bit of "Tube Stuffing" since they were more or less obsolete tubes by 1932. A type 83 sounds strange as it's a mercury vapor rectifier, are you sure it isn't an 83V? A 5Z3 sounds more typical for the power requirements, though maybe they used an 83V on a different production run?
