    66mode coke. So they act in combination with B4105 as a lowpass filter who  
    77removes incoming RF on the audio lines. I also would combine R4119/20 and  
    8 R4121/22 (39 pF+18 pF) to one 56 pF capacitor (like the EMI filter in the 
     8R4121/22 (39 pF+18 pF) to one 47 pF capacitor (like the EMI filter in the 
    99earpiece path) so we can remove at least one unique component from the BOM. 
     10(56 pF would be closer to 39+18 pF, but 47 pF should be good enough.)
