This The multi-purpose Amplifier using TDA2030. It is have power 8 watt (RMS) at 8 ohm loudspeakers. It is have low noise be valuable THD (Total harmonic distortion) 0.1% , When friends use Power supply Voltage Source 28 Volt at 4 ohm loudspeakers have output power 12Watt. But be high class the noise increases to are 2 times. Besides still three be usable with Volt supply about 9Volt , but there is the electric power is down respectively. The VR1 use for Volume popularity le....
