Electrocompaniet AW 75 idling current

OK, thank you.
Now, I have 2 more questions, sorry if I ask stupid questions.
In feedback circuit on boards this amp have 8,2K and 220pF but on circuit diagram is 47pF?
In zobel on board is 3,9 ohm and 0,1uF but on circuit diagram there should be 1 ohm.
What is better?
