KRK VXT-4 monitor repair

Hi guys.
I'm trying to repair a KRK VXT-4 near field studio monitor.
I have searched the internet for any schematic for this monitor for a long time but couldn't find anything.
The HF driver (LM3886) blew up and needs replacing. Now, the main amp pcb is covered with this nasty black silicone, and I had a hard time to get it off so I could see what's going on in there.
I am stuck in identifying the part number of Q1 on the amp board (or main pcb).
Maybe someone here cold help me with that.
Of course, the complete schematics would be excellent as well...
