Model 5900 Power Oscillator




General Description


The Model 5900 is a high general purpose audio generator.


The circuit consists of a low distortion oscillator, a drive amplifier, and a bipolar FET class AB1 power amplifier with an output transformer.


The output transformer has three taps to allow utilization of the full power over a wide range of voltages.


A frequency counter and output voltmeter are built in. Electronic overload protection is provided that limit the power into a short circuit to a safe value.
