1310-A
The General Radio 1310-A Oscillator was introduced in Catalog S (1965) and remained available through Catalog T (1968).
The Type 1310-A is a RC Wien bridge oscillator driving a low distortion amplifier. With a constant output independent of frequency but adjustable from a panel level control. The 1310-A is a hybrid design with a nuvistor triode as part of the oscillator bridge and the amplifier using transistors. On the side of the instrument is an combination input/output synchronization jack. Although its output impedance is 600 ohms its also useful with 50 ohm applications.
