RE: "work at lower values...?"

Posted by Lew on February 17, 2017 at 10:13:28:
Of course you won't hurt anything, but inevitably you are changing the -3db point. Whether you can hear the difference or not is quite another subjective issue. However, the difference is there for sure. Once in a while, I have found it possible to get away with a lower value coupling capacitor where it is also possible to double the value of the resistor that goes to ground, in a coupling mode. In THAT case, you don't change the -3db point. IOW, 0.22uF with a 500K resister is ~equal to 0.1uF with a 1M resistor, in terms of the -3db point.
