Narrative:
Atx X departed alb stopped at 7000' on arwy for crossing traffic at 8000'. Another atx Z departed, stopped at 3000' for 3500' VFR traffic. I informed atx Z VFR traffic no confign and climbed maintain 10000'. The readback was 'atx Z roger, 9.' the '9' was just finished; I didn't hear the slur. The next thing was the C/a ring and atx X had climbed to 9200' climbing to 10000'. He had small transport Y traffic opp at 9000'. I gave traffic alert and atx X had him in sight and was instructed to maintain visibility, but sep was lost. Atx X had climbed from 7000 to 10000' west/O ATC instruction and I didn't catch him prior to the C/a's going off.
