A good general purpose stereo audio amplifier using the BA5406 monolithic power amplifier IC. Can be used on it's own or incorporated into existing equipment.
Supplied with components for either 28dB (standard) or 46dB (high) gain. The standard gain option is ideal for general audio applications and will be more suitable with most pre-amps or PC sound cards, etc.
Volume control is easily achieved by adding an externally mounted dual gang, logarithmic potentiometer of between 10K Ohm and 50K to the audio input.
Supplied with all components INCLUDING heat sink. Speakers and cables are NOT included.
See 3090 for the same product supplied WITHOUT a heatsink.Specifications
