The General Radio 1309-A Oscillator was introduced in Catalog T (1968) and remained available through Catalog 1973.
The Type 1309-A is a solid-state sine and square wave oscillator with low noise, hum and distortion suitable for audio applications. Its frequency and attenuator controls are arranged in decades. The last position of the attenuator provides the square wave output. On the side of the instrument is an combination input/output synchronization jack.
