The audio section. The plate of the triode goes through a 220 k ohm res to low current B+. The plate also goes through a .01 mike cap to the grid of the audio output tube. This grid also goes through a 470 k ohm res to ground. The cathode of this tube goes through a 120 ohm res to ground. There is a 20 mike cap in parallel with this res. The screen grid goes to low current B+. The suppressor grid is internally tied to the cathode. The plate connects to the bottom of the output transformer primary. The top of the primary connects to high current B+. There is a .001 mike cap in parallel with the primary. The secondary of the output transformer connects to the speaker voice coil.
