Used in carrier amp lifer of strip-chart recorder to provide amp litude-stable fixed excitation frequency for transducer. Two-stage amplifier with 360° phase shift oscillates when output is fed to input, al frequency depending on loop parameters. Amplitude variation is held to 0.2% for 25℃ change in ambient by simple zener and transistor limiter.-Amplitude-Stable Audio Oscillator, EEE, 11:8, p 87.
