And...have you tried to change the speaker?
Leave all in place, only disconnect the voice coil from the output xfmr secondary and connect a PM speaker to it. See if the distortion persists.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
