 I didn't want post the whole schematic for copyright reasons, but  they used a Stereo Headphone socket, insulated, Double Pole Double  Throw -Switched , with 330 ohm 1W  series resistors  fitted to the headphone side to protect both the headphones and the listener, as well as give a more suitable output level to the headphones .

What's the spec on the resistors, carbon, wire-wound or metal film? This Metal Film from Mouser is rated for 50ppm drift, so when push comes to shove, the resistor may not break down and the image should be pretty good.

 

Also found an article that explains when HPs can be connected directly to power amps, others require resistors as above. Interesting topic.
