(Created page with "The '''General Radio 1311-A Audio Oscillator''' is a transistorized Wien-bridge audio oscillator with transformer output. ==Specifications== * 11 fixed frequencies – 50, 60, 100, 120, 200, 400, 500, 1000, 2000, 5000, 10,000 Hz selected by rotary switch. A vernier provides a ±2% adjustment about nominal. * Power: 1 W into matched load. (Taps provide at least 0.5 W output into any resistive load between 80 mΩ and 8 kΩ). * Voltage: Continuously adjustable from 0 to...") |
