NS-40 Receive Audio Muting problem

I recently did the "Tuning Pot Retrofit", I believe successfully. However I have noticed that my receive audio is down. 

When I touched (by accident) my scope probe to the ground side of the audio mute connector the little baby came to life and literally jumps in the table.

Since the audio mute line is supposed to mute the audio when the line is grounded, I'm assuming the circuit is cadywhompus!!! Perhaps the J310 is bad? I'm at a loss?

Any ideas???
