Well it looks like the B+ lead from the audio is disconected. It should be a red wire. To double check measure the resistance from the red wire to the plate pin of the audio output tube. Should show a few hundred ohms or so. If it does the red wire would connect to the + side of your second filter cap. With this disconnected the will act dead NO AUDIO at all.

figure out what all those squiggly meant.

Now I think I've got!
