Hello guys, in this post I make Quad bridge 4 channel amplifier, which can deliver up to 49 watt output per channel at 4 Ω . For this amplifier I use TDA7386 IC but you can use TDA7388 IC instead of Tda7386 IC. But if you use TDA…

Hello Friends, in this post I make a 200W mono amplifier. This is a class AB mono amplifier. Which can deliver up to 170W RMS output at 4Ω ±35V, Test frequency 1khz. And 130W RMS output at 8Ω ±40V, Test frequency 1khz. This IC is…

Hello Friends, in this post I make a 300 Watts mono amplifier. This is a class AB mono amplifier. Which can deliver up to 270 Watts RMS output at 4Ω ±65V, Test frequency 1khz. And 200 Watts RMS output at 8Ω ±70V, Test frequency 1…

Hello Friends, in this post I make preamp board for "Dynamic" microphone. For this preamplifier I have used UA741 IC. But in place of UA741 IC, you can also use TL071 IC. For designing my PCB, I used EasyEda online soft…

Hello Friends, In this post I make a 200 Watt mono amplifier using 2 pairs of 2SC5200 and 2SA1943 Transistors, which can deliver up to 160-watt RMS output at 4Ω ±35V. The low-mid frequencies of this amplifier are very good. And o…
