Scott:

Does the speaker make any sound at all? I see in your previous posts that it did at one time. If you are getting good voltage measurements then the field coil should be ok. You might want to check the output transformer. Try injecting an audio signal through a small capacitor to the top or middle of the volume control. Ground the other side of audio source wire to the chassis.
