I've got a simple audio circuit that I wouldn't expect to have any signal coming out of it (the resistor at the input is a pot and is being grounded out). But the previous stage's signal is still coming through: http://img399.imageshack.us/img399/5804/opampinterferenceaz8.png [Broken] * It's not the contact resistance of the pot; I've soldered the terminals directly together and it's still there. * 1/2 Vcc pin is perfectly flat relative to ground. * Increasing the electrolytic cap didn't seem to have any effect * There are two of these, and the crosstalk on one is higher amplitude than the other, though all the values are the same * The crosstalk increases as frequency increases So I'm suspecting some kind of inductive pickup in the pot (20k resistance)? Does that sound likely?
