Hello Friends, in this post I make a 400W mono amplifier. This is a class AB mono amplifier. Which can deliver up to 320W RMS output at 4Ω ±65V, Test frequency 1khz. For this amplifier I used 4 pairs of 2SC5200 and 2SA1943 Transi…

Hello guys, I make a 2 band stereo tone control board in this post. In this tone control board, you can control high and low frequencies. You can use this tone control with any amplifier for its low noise distortion. For this t…

Hello Friends, In this post I make a stereo amplifier using a pair of 2SC5200 & 2SA1943 Transistors. which can deliver up to 80W output per channel at 4Ω ±45V. For designing my PCB, I used EasyEda online software. Then I exp…

Hello Friends, In this post I make a 800W mono amplifier using a pair of C5198 & A1941 Transistors. which can deliver up to 80W output at 4Ω ±45V. For designing my PCB, I used EasyEda online software. And then I go to  PCBWay…

Hello Friends, in this post I make a 3 band stereo tone control. For this tone control I have used NE5532 IC. But in place of NE5532 IC, you can also use TL072 or 4558D IC. In this tone control, you can control the high mid and …

Hello Friends, In this post I make a 80W stereo amplifier using TDA2030A IC and C4793 & A1837 Transistors, which can deliver up to 80W RMS output at 4Ω ±16V. The sound quality of this amplifier is very good. All frequencies a…

Hello Friends, in this post I make a Bass booster. You can use this bass booster with any amplifier. For designing my PCB, I used EasyEda online software. And then I go to  PCBWay  to manufacture my PCB. PCBWay is the largest PCB…
