This shows detail electronics schematic for ZN414 AM   designed by Harry Lythall. This device consists of a single transistor mixer then a ZN414 radio IC to provide the gain and detection. A 741 OP-AMP is used as the final audio stage, but this could be replaced with an LM380, if you want to drive a small loudspeaker.
