Narrative:
Aircraft X in a string for the downwind landing north. I thought I issued 9;000 ft. Because the MVA (minimum vectoring altitude) is 8;500 ft. I saw aircraft X at 8;300 ft. And told them to climb immediately and bungled up the phraseology while attempting a safety alert (which did not go off). After reviewing the replay; I actually had issued aircraft X 8;000 ft. I can only assume 8;000 ft. Was on my mind because when I base aircraft I give them a heading of 180 and 8;000 ft. I issued the incorrect altitude and attempted to catch it before it was a loss with terrain; but did not. Although multiple things were going on; I should have been more vigilant in my hear-back.
