Also need to verify all the resistors.

The radio originally used a high impedance magnetic speaker. Trying to run a low impedance PM speaker without an output transformer would be too low of a resistance plate load on the output tube.
You'd have to consult a tube manual to see what the plate load is needed for that particular tube.
