Wien bridge oscillator

01:01:02

Frequency ~ 233 mHz@~4V
Shake to start (inject noise)
There is non-linear stabilization made with antiparallel diode

Check this and see your gain is 2.99...... and not 3. So no need to use diodes because the oscillation will die out anyway. You have to increase the gain only a little above 3 and can than make use of the non-linear diodes. Keep it up

Search here for "opamp gain" and look for "1 plus 2 is not 3"
