inverted position of Q7

[kt315]

hello,

may be the matter was discussed and I missed something, so pls give a direction or link.
why Q7 is installed at original board (pics of Alexis) in inverted position? it is not acceptable, in my opinion, for MOS-FET.
mistake or norm?

regards

are you sure it is Q7 and not Q2

as i remind Q2 is inverted 2n2222 on silkscreen becaus there is a metal can and a plastic type of this part


with Q7 placed on pcb like on the layout it works

the silkscreen of Q2 on board is OK. in Alexis's part list Q2 written as 'PN2222', that is clear plastic type P2N2222A.

if works I leave Q7 as is, though later have to check it in both position. curios that american standart of drawing is to image a MOS-FET like
simmetrical SOURCE-DRAIN pins position, but a structure on chip/crystal is not so symmetrical in real.
