[Hexhclass]

I track down the -31v it is coming from Q126.
Q126
1:-31.3
2:-31.1
3:-31.1
I pull it out and it is not shorted.Can i replace it with DJ23AA ( Q126 is pzta56)

The number you posted is not part of the part number. It's likely production code. The number (A56/A06) is what's important.

Q126 has D446 printed on it.It is a surface mount type

 

[Perry Babin]

This is from a different amp but you can see that the numbers you're posting are the top numbers. Those are irrelevant. The bottom numbers (A06/A56) are the part numbers.

Ok i understand.I will replace Q125 and Q126 to see if i get any change.They are not shorted.I think they are leaking and my meter is not picking it up
