What is also puzzling me: why are there two anti-pop circuits? The only reason for two series resistors (instead of just connecting both tip and ring via a single resistor to the amp output) I can think of is that there’s still some signal at the tip when a mono plug is inserted. But why two MOSFETs? Using a single resistor instead of R646/R647 and a single MOSFET would have done the trick too, no?
