R.G.	Re: Ghost Noting By the way, Ray, one thing you can do that will drastically change the power stage's effects on the pre/PI sections is to put a 1N4007 in series with the first resistor Pi-section. This keeps the power amp from draining back the voltage from the preamp on peaks. In the PI, you can do something similar by using a diode in series with the choke, but you have to have a diode reverse biased to ground on both sides of the inductor to let the inductor clamp to ground in case the current ever goes discontinuous. It keeps the power amp current drain out of the PI's knickers.
