Thank You Nathan for the reply. Your radio looks good. You sure took a lot of pictures, and I am thankful for that. It looks like I have it put together right. After seeing how yours looks with the lights on, my tuning dial is definitely not right with the dial that I have. Apparently the center section of the tuning dial must have broken out, and someone made a repair by cutting a piece of sheet metal to replace the broken center section. This blocks all the light from entering the station tab area of the dial. I have a second chassis, but the dial is in even worse shape than the one on this chassis. For now, a good reproduction is not available, and may have to live with what I have or install a less desirable reproduction.
I am still trying to work out the hum issue from the hub. l may not have that assembled just right. It does mute when the tuning crank is pushed in, like it is supposed to, but somehow the center hub is not insulated from the muting circuit like it is supposed to be causing the radio to hum when the dial is touched just right. I will look through your pictures and see if I can pick up a clue as to what is going on there. Is there some kind of insulator around the switch contact that fits around the shaft? I have the insulating washer that fits between the hub and the contact, and think it is installed right. But it looks like the contact is touching the crank at all times, and can rub against the sides of the crank mechanism.
I took lots of pictures as I disassembled, but really don't know if it was assembled properly as the radio was dead when I got it.
I will take another look at it next weekend.
