Thanks Ed,
First, I rewound the small antenna coil as it was open. Stronger signals now, but no change in the dropoff symptom.

I have rewound about 5 osc coils already. I just pulled this one out, someone already has attempted a rewind. There's about 14 turns on the outer winding, I believe Ron says 18T of #38 wire.
Going to do the rewind and see what happens. I am deciphering the previous work, and it appears it may have been wound CW instead of CCW.
Would the set still work somewhat (it is sensitive, and sounds ok otherwise, except for the dropoff on the high end) if it was wound backwards?
Looking from the bottom, starting at terminal 3, it is wound CW going to term. 2. So I' am going to make it, right and a much cleaner rewind. I use old strips from photogaphic film as an insulator.
Swapped out the 6A7 tube, no change.

Will check back later this evening. Thanks!
