Perhaps this should be called the Penultimate Receiver page, because I have a feeling there will be another "ultimate" regen around the corner that I must build.
The detector circuit, first AF amp and 2nd AF amp. In between the two amp stages are connections to the audio filter (Select-O-Jet). This can be bipassed.
As I've written here before, drawing the schematic of a project helps me be more familiar with the project and, hopefully, leads to understanding what is going on in the circuit.
