This is a miniature 0.7W amplifier with adjustable bass boost, gain, and volume controls. Uses 1/8" (3.5mm) headphone jacks on the input and output. Powered by USB or 9v (4-12 VDC, max of 15 VDC). I designed it to use film capacitors and Nichicon audio grade electrolytic capacitors wherever possible in order to preserve the signal and reduce noise. An isolated power supply such as a battery is...
