2 wires on the antenna transformer were reversed, so I switched them back and the signal was much stronger. When I put my finger on the #6A7 tube the volume increased slightly so I figured there may still be an issue. It looks like the shadow meter is sporadic. I removed the shadow meter to test the coil and it seemed to work fine. I hooked the 2 ends to a 9 volt battery and the needle turned fine, and no loose or broken wires.
Then I put it back together and turned on the radio. After waiting for the radio to warm up I turned the dial to see the shadow meter working fine, but then after about ½ hr I switched the channel and the shadow meter didn’t move at all. I went through the entire cycle of stations and the shadow meter didn’t move at all. So I’m thinking that maybe the electromagnet’s wires in the shadow meter are just old and should be replaced?
If that’s the case I don’t know if I can buy one? Or maybe re-wire it?
