Thank you for your help, Joegio. But how do I incorporate the resistor into the formula (e.g. resistor of 15k ohm)? Is that just added to the amplifier's resistance (33,000 + 15,000), changing the equation to C= 1/(2*Pi*130*48,000)? Or is there another formula to incorporate the resistor? I know that this can be done without the resistor, connecting the ground directly, but based on a Stereophile prototype (Corey Greenberg Vol. 17 No. 1) who incorporated a resistor as well, there "must" be some advantage to that. Does anybody know?
