Regarding the schematic, part labeled 43 - .02 mfd capacitor feeds back to screen grid G2 on the 12SQ7 first audio tube. Some Zenith radios have this also.
Question 1: Is this de-emphasis feedback to increase low-frequency response? Question 2: RE Part 38, Often the 35L6 audio output cathode resistor can be bypassed (paralleled) with a 100mf-16v capacitor to increase bass. Does part 43 accomplish this?
