Befaco Rampage build problem

I just built a rampage and when i powered it up I noticed the rising and falling gate outputs weren't working. On inspection I saw I had a transistor installed backwards (2n3904 NPN transistor) on the cotrol board.

I removed it and reinstalled it correctly but the same problem persists, it looks like the transistor is broken can anyone confirm this is likely?

Any help much appreciated!

I think i got a similiar problem due to wrong transistor placement on the control board (T102 - 2n3904) but for me the whole slope A section doesnt work. Did you solved your issue and how?

Actually i missed to solder one side of an resistor in the slope A section - now everything works smile except the output led off slope B ... ?!

Perhaps the led is backwards as well.
