The detector. The top of the secondary of the i f transformer goes to both diode plates of the duo diode triode which is the detector and first audio tube. The cathode of this tube is grounded. The bottom end of the i f transformer goes to a point we will call detector. The detector point goes through a 220 k ohm res and a 100 pf cap in parallel to ground. The detector point also goes through a 2.2 meg ohm res to the AGC point. The detector point also goes through a .01 mike cap to the top of the volume control 500 k ohm audio taper. The bottom end of the volume control is grounded. The wiper goes through a .01 mike cap to the grid of the triode section of the detector and first audio tube. This grid also goes through a 10 meg ohm resistor to ground. End verbal description.
