Replacing David Clark Aviation Headset Left Dome

简介

I received this headset at a garage sale. At 10$ the price was right. From comparing picture on the internet this seems to be a H10-36 set. That is the best identification I could find. The headset has seen better days and was well used. Both the left and right dome were loose, the left dome was cracked, and there was a suspicious rattle in the left dome. One of the pins to hold the dome to the stirrup had broken out of the dome. The boom microphone as well as the mic mount on the dome, were missing. The crossover cable had been previously repaired and was just hanging between the left and right dome.
