Where did you measure the two different signals? C8 produces only one signal.
Good, you have an audio output at 1kHz. But its level is very low and it is very distorted, the same as when my FM clock radio is not tuned to the center of the radio frequency. Try increasing then decreasing the tuning capacitor values or the tuning inductor values one at a time. When the signal level increases then you are getting the tuning closer to what it should be.
