Narrative:
Aircraft X arrived at gate with pilot write-up 'captain's boom microphone broken' and pilot item #2 'observer's headset broken.' there were 2 additional write-ups concerning cabin items which I repaired. The captain's boom microphone and observer's headset parts were not in stock here in ZZZ. Since there was an FAA jumpseat rider; I told the captain I could go to the hangar and retrieve both parts off a spare aircraft. It was departure time now. The captain and observer said they would make do without. I deferred both the captain's boom microphone and observer's headset to be replaced when parts available. The captain's boom microphone should have been MEL'ed under 23-5104 and the observer's headset under 25-1106A. It never occurred to me both items needed to be MEL'ed. Captain's headset/boom microphone was a class 'a' MEL. This was clearly an oversight on my part. The human factor was time involved and me rushing to get the aircraft out on time.
