Sorry for any faults or ambiguities! Once again:<br>
<br>
change R4303 (oh-three) [0R, MIC4301:2 to GND] to 2k2<br>
<br>
R4304 (oh-four) is not in the published schem [any more], it's obviously been<br>
replaced in schematics by C4306 [NC, MIC4301:1 to GND]. However you may find<br>
R4304 in component placement diagram (you won't find C4306 there!). It's the<br>
two empty pads left side of the component array left to mic. Symmetric to<br>
R4303.<br>
<br>
<br>
If you want to retrofit C4306 with a huge capacitor, you could use the empty<br>
pads of R4304 to connect it. You also *have* to make the R4303 0->2k2 change,<br>
otherwise mic signal is shorted by this capacitor and you won't see decent<br>
signal on mixer input.<br>
