I have a David Clark Active Noise Cancelling H10-13XP that I would be willing to part with. The only downside is that it is panel powered. The panel power supply came out of Woodstock and can be installed into another aircraft. There is no battery pack for it. It would be part of that aircraft.
Here [
aircraftspruce.com] is the ad for it at Aircraft Spruce. My wife and I upgraded to Bose and installed the panel mounts for those as well.
