Made a balanced line driver out of the output section of the compressor.

I'm feeding the op amps with +/-15vdc.
I get -12.5vdc at pin1 and +12vdc at pin 7.
Measuring the outputs, past the dc block capacitor, "-" reads 0vdc and "+" reads +11vdc.

I've swapped the output capacitors, and still getting dc at "+".
Whats up with that?
 
Missing 30K Rin (27K from schematic in front of the VCA) connecting to inverting input pin2 ?
The upper 100uF probably blown from reverse biasing.
