I got the double peak alignment part to work by:
1- Discovered that "Fidelity control in expanded position" means turn the Selectivity/Treble control Counter-Clockwise.
2- Wearing hearing protection and increasing the volume to full and setting the signal generator output to high.
The other key was all it takes is minuscule adjustments on the 94P coil, and sure enough, you are able to get dual peaks 5khz eeither side of the 470 khz IF.
