The General Radio 1311-A Audio Oscillator is a transistorized Wien-bridge audio oscillator with transformer output. The switched output frequencies correspond to commonly used bridge generator frequencies. A delta frequency control is available on the front panel to fine-tune the frequency. Although designed as a bridge oscillator, the 1311-A is also well suited for audio testing, given its low hum and distortion levels. As a bridge oscillator, it is part of the [[1660-A]] Inductance and [[1620-A]] Capacitance Measurement Systems. | The General Radio 1311-A Audio Oscillator is a transistorized Wien-bridge audio oscillator with transformer output.
