Hello colleagues, I am looking for the name of this transistor (Q2) if someone could provide it to me, it would be very helpful greetings is for a hifonics amplifier Model RE1600.1d greetings

Mr. Perry I already got the transistor, thanks for the info but I have more problems the amplifier is in protection and I have the amplification stage out of the board, already check the PS fets and they are in good condition I realize that pin 3 of the 494 is higher, I don't know what is causing it, I see that the voltage of pin 1 is higher than 2 But I can't discover the cause, what else should I check?

Thanks
Now the part of Ps has already been solved, but now in the output stage the board has too many problems sorry for focusing on the foreground only to the PS stage but apparently this amplifier has a monstrous disorder, on the output driver board fast the resistors flew 8,34,35,26 and the D1 so when they turned on they flew, it remains to replace them and investigate the root cause and in the case of diode 1 which one did he place? what model?
