1 kHz Wien-Bridge Oscillator

The starting pulse is generated by the positive power supply’s startup slope.  If the power supply does not slew fast enough  the oscillator will not start. R3 can be increased to increase the gain and likelihood of starting.  It also increases distortion when  the amplitude as the peaks aproach the power supply rails. (Circuit is created by John Bishop  based on a design by Neil P. Albaugh.)
