Here's the schematic for this radio, as you can see on the schematic, this Radio's Output Transformer's Primary is indeed center-tapped, because the output transformer's primary measurements are taken between the two outer leads and the inner lead doesn't have measurements to it, meaning its center-tapped.

The speaker on this radio is a permanent magnet type speaker with a 3 Ohm Voice Coil that has one side grounded to the chassis through the housing of the speaker, the ouput transformer has a 200 Ohm center-tapped primary and a 0.6 Ohm secondary that has one side grounded to the chassis through the transformer's housing, that's what the schematic says anyways.
