Help req please - Identifying SMD transistors

Hi, i have an unidentified circuit board which i'd like to replace
completely by making my own. It has a couple of SMD transistors.
1 with the markings " A6p " with " 21 " at right angles to this
1 with the markings " U1p " with " 19 " at right angles to this

Any help would be really appreciated
