That's interesting - one to lodge away for the future...
As you might already know, the wiring to the loudspeaker and headphone socket changed at some point, and as a result, the 10Ω resistor was moved to the negative tag of the loudspeaker, and 3 wires (rather than 2) went to and fro between there and the headphone socket. This means that the headphone ground now came from the amplifier output connections rather than the chassis - which seems like a good move to me.
