1940 Ford Zenith Radio

Hey all, so I've been working a bit on my original 1940 Deluxe Fordor's Zenith radio. This radio looks pretty complicated, but I wanted to see if I could get it to work. But I've run into some issues.

1) I replaced the dials with new repro ones as the originals had cracked and were turning to dust. But something didn't seem to work right. The volume dial turns great and the left pre-set station selector dial turns. Granted, I don't know if the dial is in the correct spot where it should be. But the problem is the right side station selector and dial do not turn together. The gears from the two are not the same size. Plus, trying to turn the knob is tight and not easy.

2) When hooking the radio up to a 6v power supply, I can get the internal lights to come on and there's a buzz from the speaker. The speaker itself vibrates a bit. It seems like it's working, but there's no sound. I've tried turning the dials, but nothing seems to work. Any tests I can try?
