I'll check these when I get the amp back on the bench.

 

[Perry Babin]

Check R533.

 

[mike49504]

Where is R533 located there are no board locations on alot of them

 

[Perry Babin]

See attached. If it's within tolerance, measure the DC voltage on both ends of it.

 

[mike49504]

Ok i believe its suppose to be a 10 ohm resistor it measures way out of tolorance so i will pick 1 up later today.

Do you know the values of R321 and R309 ? They are located on the long input board right by all the surfacemount IC's

 

[Perry Babin]

309 is 10 ohms. I don't see 321.
