Without checking Chip's calculated values, it would be around 250uF, for the 5 Hz cut-off he chose. The simplest way to look at it is that the values of Rk and Ck multiplied together should be a constant for a given desired cut-off frequency. Note that 50uF*1000R is roughly equal to 500uF*150R (the numbers Chip chose; obviously you could use a 450uF or 400uF cap with the 150R resistor for a result closer to that which you get with Rk = 1000R, or you could use a 100R resistor with 500uF).
