It appears that is not the fairly simple mod proposed by Dallas  
Lankford in Hsn #23.   That mod is touted to be the single most  
effective simple improvement that can be made to the R-390A.  Two  
diodes are simply added to the circuitry.

The AGC mod you refer to may be the much more complicated one. I have  
not done it to any radio... yet.
