89 Hz Wien bridge oscillator output signal does not appear
I believe Wien bridge oscillators need a theoretical minimum gain of 3 to sustain oscillations at a constant amplitude and, at start-up, you might need something like a gain of 4 or 5 to initiate oscillation. Try a higher gain is my advice - make R4 more like 20 kohm and see if it starts.
Next is to add amplitude control to keep the sinewave all pretty. Then get rid of the dinosaur 741 op-amp in favour of a much better device.
