That was the original idea, but I don’t think the jacks installed fit any headset at all. The headset was discontinued. You’d have to get the plugs reconfigured. There are some posts on this way back when.
The power jacks are for some headset configurations that are available where you have a 3rd plug for power, rather than using battery after battery after battery…
I plan on obtaining the mating plugs (I have the part number) and wiring them to a little “battery eliminator” that will go into my existing (battery powered) Bose Xs, giving me the best of both worlds. Powered by aircraft in normal use but usable with a 9v battery an in emergency or in other aircraft. Plus I’ll save the cost of having my Bose Xs converted.
Once I’ve built one of these and tested it I’ll post the design here a la the approach chart clip.
