I have a new choke on the way. For now, I have a 400 ohm power resistor temporarily installed until the choke arrives.
New problem, when installing the tuning dial and shadow mask, are the 4 lamps that go around the perimeter of the dial assembly, supposed to be directed onto the back side of the dial face, in between the dial and shadow mask, or directed to the back side of the shadow mask? The dial has been repaired by a previous repairman, with a sheet metal center hub. No light can get thru to the station tabs with this dial. I am assuming that the center needs to be somewhat translucent to see the tabs. I will just have to make due until I can get another dial face.
Another issue is that I am getting a hum from the center dial cover, when it is touched by hand. I assume that the muting switch is somehow shorting in the tuning knob assembly. I don't see any way that it would be insulated from the mute wiring, unless I am missing a component in the dial assembly.
