Can we assume that you have searched around the board and seen that there are no other ADKX like Q series units being used on the board.
If so, use that one(s) to compare like tests against.
Digital transistors with their internally isolated base resistors are a problem to positively evaluate and test , unless you pull them and do an off board gain/ BETA test on them .
HEY ! . . . . . .
I just now remembered I HATE trace routing analysis on . . . . . . GREEN ON GREEN PC Boards, and also BLUE ON BLUE boards, but even WORSE are BLACK ON BLACK with maaaaaany
crossing vias between front and back planes. This board FULLY fits those criteria.
