Schematic here I think this is your set :

You may be able to scare up a clearer image and more information elswhere

I'd check the plate voltages (measure to B- rail) and make sure the output transformer and field winding is good and and wiring is OK. Well, then it's just a mater of working backwards from the speaker to find the point of failure. Frankly I wouldn't trust any of the carbon resistors in a set this old, no matter how they measured cold.
