Background:
I have a portable TV which I want to add a headphone socket to.

Plan:
Open TV.
Find wires (probably just 2, I doubt it a 14", £80 TV has stereo)
Add chassis mounted switch to the live (?) wire.
Add chassis mounted headphone socket to the casing
Wire the socket to the other 'side' of the switch

This will (I hope) leave me with a TV which I can switch between
headphone and speaker modes.

thoughts anyone?
