I agree with Dave, make sure you have sound across the new 47K (which replaced the 50K volume control) first. If you do then, check the connections to the switch.

Looking at your diagram I see that you have C48 which is not in the stereo version, so you could try taking one lead off that, since it might be attenuating the 19KHz pilot tone.
