This is what I would have a look at. The avc voltage as you tune across a station not WLW . Does it drop more - as the station gets stronger? Since you have a strong station near by it might be driving the avc voltage - all the time. Use a battery powered audio signal source to test the audio stages to determine if the gain is low and if the distortion is coming from the detector.
With #20 bad you had pretty much no screen grid voltage on the mixer and the IF amp. This would make the gain VERY low. Surprised it would do much of anything.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
