Creek 4040s2 need resistor value

Hi folks!
I need some help.
I have this little neat amp and there is a resistor burnt.
I can't find it on the schamatics because this section is not on it.
The resistor is placed between the volume potentiometer and headphone socket.
It is connected to the groundwire which is soldered over all potentiometers.
Can anyone help me with the right value?
Many thanks in advance!
