Narrative:

The inbound air carrier X experienced a slat problem channel #2. Our radio electronics technician requested my assistance in deferring problem per MEL. We pulled up MEL and both agreed that our problem matched MEL 27-XXX and performed test as prescribed; which resulted in pulling and collaring circuit breaker. On arrival of flight at ZZZ1; crew experienced channel 2 flaps (circuit breaker out). Item changed to MEL 27-xxy. We felt we used correct MEL and test was satisfactory. I have since reviewed MEL and determined that in fact we did use wrong MEL. I feel that stress might have been determining factor as both the radio electronics technician and myself had been working outbound aircraft which were having unusual problems; and we were shorthanded and working against the clock.
