A good general purpose stereo audio amplifier using the ROHM BA5406 monolithic power amplifier IC. Can be used on it's own or incorporated into existing equipment.

Operates on a simple 5-15Vdc single rail power supply.

Supplied with components for either 28dB (standard) or 46dB (high) gain output. The standard gain option is ideal for general audio applications and will be 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 input.

Supplied with all components (except heat sink, speakers and cables).

See 3090H for the same product supplied WITH a heatsink.
