Troubleshooting Nurse Quacky

I don't know if this could be the problem but the way the layout is drawn could be confusing.
The connection from attack 2&3 should go to the same row as range 1, on the layout it could look like it goes to the row above with a jumper to the row below. If you wired it up like this it would drop the bias voltage to 2 volts or so and stop the envelope follower working.
Here's how it should be wired up

You are correct! I have both of those traces wired together as that's how the layout seemed to show it. I'll fix it and see what happens!! 
Thanks.
