Mod for G3 Blues Amp, headphone connection, somebody has done that already?

Hi all,

I want to extend the G3-Blues Amp with a headphone extension.
Of course with some load (8 Ohm, 10W resister?) to compensate for the speaker that is disconnected during headphone use.
Has somebody done this already?
All tips are welcome.

Thanks.
