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)
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
