Model 5900 Power Oscillator
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.
