Oscillator with precise amplitude

Hi:

Try looking at this. Is the JFet turning on hard enough to reduce / regulate the gain? Maybe you have an inversion somewhere along the amplitude control loop that is increasing the gain rather than reducing it.

Hi,

Thank you for your answer. I tried to put a signal in place of the Wien bridge ; the output does not saturate but it still doesn't work. The value of Vset doesn't change anything.

I think there is a mistake in the doc?

Thank you
