"William Sommer******"

I did a little spread sheet and came up with the following
capacitances for 20 KHz and the three resistances:

600 ohms 0.066314561 uF
2,000 ohms 0.019894368 uF
13,000 ohms 0.003060672 uF

Arny, why didn't you round off these values?



** Maybe Arny was having an attack of digititis ....
