Most tube radios with push pull outputs used class A, though some used class AB, and some used class B (class B in battery radios mostly). None of it is really relevant to restoring a radio, it has more to do with how the tubes are biased and with power consumption. Some would use an audio interstage transformer to drive the output tubes but many later 30s sets used a phase inverter.
