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…
