This morning I finished off a little bit of priming that I did not complete yesterday then opened the holes in one headset jack mount to accept LEMO sockets for powered, active noise reduction headsets. I'll need to modify the centre console to fit this third mount as I intend having two sets of traditional G/A sockets in addition to these. Not sure which brand of headset at this stage but at the rate of my build there will be numerous new models available by the time I need them.
