After the recap, I powered it up and got some weak, garbled audio. Time to investigate...

Eventually, I noticed that one lead to the internal loop antenna had broken lose

Much better gain now, but it's still garbled. I tested the one mica cap and found it to be shorted.
Replacing it did the trick - great sensitivity, selectivity and it sounds pretty good


Next, I went through the alignment procedure, and found it didn't really need it.

Finally, I'm going to clean it all up.
I used some glass cleaner and Q-Tips on the glass dial


The metal dial backplate was rusty and discolored form the pointer sitting in the same position for so long. I carefully unmounted it and removed the rust with naval jelly. Than a litte sanding and primer. Once that's dry, I'll used some metallic copper paint.


I also restuffed and repaired the filter cap.
