Unless you know your electricals and have the time, Richard Holder
[email protected] will do it for you. £160 plus £10p&p fitted and +£10 if you want the battery saver fitted. Richard system is an adaptation of the Headsets Inc system. The battery box for example is smaller, neater abd comes with a handy clip.
Yes its a lot of money but as I found out yesterday when I forgot to turn the ANR on, it is very difficult to hear radio transmissions. QHH whaaat?
You may wish to consider your base headset unit before conversion should you end up having the procedure done twice. The only thing I would ask first is, are you happy with your Avcomms? I found they clamped my head more than my DCs and after a few hours, my bonce was fatigued.
