Model 39 40 Speaker value
#4

Agree 100% with what has been said. Any "universal" output transformer will probably work out OK. You might want to add an additional filter cap AFTER the 1 K power resistor, as the smoothing action of the field coil will not be there, and you could have a little more hum. 10 or 22 mf ought to do it, just make sure the voltage rating is high enough.

Since you have nothing to lose, check to see if there is any break in the coil that is open that you can get to and repair before you throw it out. Also make sure the cause of the open winding is not still present, as in a shorted output tube, bad socket, filter cap, or other component.

Good luck.
