Notes

General Radio Audio Oscillator 1311 (1311-A) is a transistorized RC Oscillator, which makes extensive use of negative feedback to attain amplitude and frequency stability of high order, as well as long-term reliability. The output system uses a multitap shielded transformer, capable of matching impedances from 0.25 to 2500 ohms. The output is well isolated from the oscillator circuitry to provide a distortion-free waveform to any impedance, including short circuit. See datasheet.

Output:
-   11 fixed frequencies from 50 - 10.000 Hz
-   voltage: 0 - 100 V
-   current: 0 - 4.000 mA (short circuit)
-   max. 1W into matched load.
