Hi Guys
It is probably best overall if Ck spans all of Rk, whether Rk is a single resistor or two in series. The alternative is to place a second cap across R-add when two resistors are used. This will keep the bias more stable with signal.
C-add should be a high value so that the effective Ck value is not reduced too far. The usual 22uF or so is pretty skimpy.
