Saba Meersburg 125

Hi,
I have a Saba Meersburg 125 which I am restoring. I would like to know what value this brown capacitor is? I cannot read the value. It is off the tone control which has the switch on the back. I do not have the schematic of this part of the radio and the capacitor needs replacing. I have attached a photo.

Thank you .015uf. (15nf) Can anyone post part of the schematic showing this capacitor. I cannot find it in schematic and I am unsure where to find it.

Thanks so much for your help Heino.
