Kieth,

Certainly one could mount a headphone jack on the back panel  - right next
to the extenal speaker jack, but if you want to wire in the resistors and
capacitors and still have the ability to use either a mono or stereo jack,
then the switch that removes the speaker cannot be the normal type switch -
if you examine the headphone jack on the schematic and compare it with the
schematic of a normal jack with a switch you will be able to see what I am
referring to - the resistors cannot be in series with the speaker, but are
good to have in series with the headphones.
