The 34 uses direct-heated filament cathodes: any AC sets would have used indirectly heated cathodes and different tubes, so this set is "its own self." The schematic shows all the voltages required to run it: your best bet would be to use one of the solid-state compact power supplies for it. Note: there is no field coil on the speaker; it's an early PM. If it doesn't sound so hot a more modern PM speaker can sub.
