My Wien Oscillator won't oscillate

[Harold_Bradshaw]

I built this Wien Oscillator circuit in my lab with two 2N3904 transistors and it works. With an 11.0V supply, it generates a sinewave signal with a peak-to-peak output of 0.18V at a frequency of 1333 Hz. By my CircuitLab doesn’t oscillate. What have I done wrong?

Thanks!

Not sure why yours isn’t working but here is a simple one that works with very low distortion.

Have you missed a bypass capacitor across the emitter resistor in the second transistor?
Wild guess really
