Both of these articles mention issues with S meter drift to less than 
zero and AGC or injection problems.

These are classic signs of bad (leaky) RF or first mixer tubes. I've checked V-10, 11, and even replaced them with known good tubes. I've checked all the resistor and cap values around the RF amp circuitry and found everything within specs. I can substitute a 6AU6 for the 6HS6 and the receiver works pretty well, but then the s-meter tends to rest below zero on 15 meters and above. It's fine on 80-20.
