Default Re: Interesting Armstrong AM detector circuit.

Isn't this just a transformerless IF amplifier with the aim of reducing the signal on the previous AGC controlled IF stage so reducing distortion for high signal levels? The only other benefit I can see is that the loading on the previous IF transformer should be reduced.
