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!

Since the schematics don't show the preamp part, maybe someone else can chime in.
If that is a ground loop breaking resistor, it could be around 10R.
Is it connected to the headphone jack ground terminal? If so, 10R should be ok.
