Amazed that this is proving so hard. See this topic on NA and ARF forums with similar ideas mentioned.

Need hard data. A well equipped test bench with signal generator and scope would be nice. Without that, try measuring the AC voltage of the audio signal on a strong station. Start at the 2nd detector, through the volume control all the way to the audio output to see where you are not getting any level control of the audio signal.

A logical approach will get to the solution sooner rather than later.
