"Sine Wave" Reference Oscillator ~ 60 cps
Each buffer has a gain of two, to help cover their losses.
Buffers prevent the RC sections from loading each other.
The buffered phase shift oscillator performs closer to the calculated frequency and gain.
Phase Shift amplifiers (PS1, PS2, PS3) each have a gain of two, which covers most of their losses.
Amplifier (OA1) provides the 180 degree Feedback, and loop gain, not provided by the phase shift circuit.
Feedback = 0 phase,
Out1 = 60
Out2 = 120
Out3 = 180
OA1 providing 180 shift.
