Hi
First suggestion: You have too many 38-643B sets. You should immediately send one of them to me.
This seems to be a fairly common problem with 1937 Philco sets. I suggest you not only check the AVC, but also suspect the AM band antenna coil. Hopefully you still have that 37-650 junker? You may need the AM antenna coil from it. This is the usual culprit when you get stronger reception using the antenna on the grid cap of the 6K7 RF amp instead of the antenna terminal on back.
Also, be sure the jumper on back is connected between terminals 2 and 3 on the four-screw terminal block (the screws labeled BLK and GND).
