Your shadowmeter may be just fine. It sounds like there isn't much change in the AVC voltage, you may just need to use a longer antenna or the radio may need an alignment.

I'm thinking that may be the case. Antenna is plenty long enough, but have not yet aligned the set. 
Hopefully the magnet has enough magnetism in it. 

Looked at the alignment info, and it calls for the use of a variable condenser of about 350 mmfd in several of the steps. What is this? The alignment instructions seem amazingly complex in this set, and call for parts and procedures I've not seen before. Anyone here recently align this set? Thanks!
