doel van R13 in B5X85A ? (Techniek Radio/TV)

Dear Friends

In the B5X85A the detector diode filter is formed by C37,R11 and C38. Diode load resistance is R13-270K connected as the diode load. Since generally the volume control is considered to be the diode load will this resistance R13 not decrease the total effective value of the volume control because in a way the resistance is connected in parallel to the volume control? So what is the purpose of the resistance R13?
