MacIntosh Plus Analog Board question

[fit2page]

Hi all,

I am new here so Hi everybody! I got some electrical skills and just start to dive into Mac repairs on 512K, Classic, Plus and SE/30. Now I got this Plus on which analog board there was an exploded Q12, which I replaced with a reversed BR103 as can be seen on the picture. I wonder if anyone can tell me something about the "tweak" capacitor on R51/R47 which seems to be put there by a former owner. This is not a factory tweak I guess.
Please let me know if you have a clue before I switch on the board again, just to be sure.

Cheers.

Nobody?

IIRC BR103 is not a direct replacement of the original and no longer available Q12.

sorry but the BR103 is not reversed in you picture, again, i think it should be the opposite of the footprint in the board.

I am sorry bibilit but attached picture of Q12 is really opposite (180 degrees turned)?
