I need the circuit board

Question

I need the circuit board that the cross fader connects to. It is for the Technics SH-DJ1200 mixer. I have fitted a new cross fader and I am encountering bleeding. If the cross fader is over to the left and i am listening to a tune on the right deck in my headphone and the right volume fader is up the tune is bleeding through. My self and my engineer believe it must be the circuit board.
