Hey, so I have an SA-9500II here where the bias balance is "off". One pair of outputs is reading 20mv bias while the other set is reading 40-60mv... I'm just trying to figure out how this would be possible, there's no audible (or visible) distortion on the scope either, but obviously something is awry with the pair that's running high. Would damaged, but not dead outputs cause this, or would it more likely be a resistor issue? From what I can tell they share a driver circuit so it's unlikely it's anything before the drivers, right?
