In previous tutorial I made a TDA2030 stereo based 28w amplifier. which is operated by external power supply. but how to use an amplifier without improper signal strength and frequency. That’s why preamplifiers come into market. Because I did not want more regulators/ wires and power supplies here in this circuit, I am making a…
I made many amplifiers and tone controlling boards in past. But most of them either work on dual mode power supply or need a lot of external components. Today, I have an idea of single power supply transistor based stereo type preamplifier. This preamplifier circuit is used to control volume, bass and treble of any…
I want to make a big party boom box, with a 100watt subwoofer and four speakers of 25 watts each. But we need a better amplifier and preamplifier board which can meet the requirements. I searched a lot but some of the amplifier systems are very expensive or some of them even do not support…
