    I measured the two 220k resistors out of the PI, one measures 220k perfect in circuit, the other 215k in circuit (Mig 100). Would this difference be enough to distort the sound severely?

    Typically, you can't measure resistors "in the circuit"....as a matter of "good habit", it's always best to disconnect one lead so that you're certain that you're measuring "just" the resistor.

    Agree and add: no, no way such a small difference can cause "severe distortion".

    I am not familiar with the amp but assume it's push pull, which helps cancel out a lot of the noise, and would maybe make this less of an issue?
