Hello Friends, In this post I make a 100W mono amplifier using a pair of 2SC5200 & 2SA1943 Transistors. which can deliver up to 70W output at 4Ω ±38V. For designing my PCB, I used EasyEda online software. And then I go to  PC…

Hello Friends, in this post I make a 50W mono amplifier using TDA1514A IC. This is a class AB amplifier. Which can deliver up to 50W RMS output at 8Ω ±27V, Test frequency 1khz.  This IC is especially designed for High-End Stereo …

Hello guys, I make a 4 capacitor power supply board in this post. In this power supply you get ±40VDC, 12VC and 5VDC output. You can use this power supply upto 1000W amplifier. For designing my PCB, I used EasyEda online software…

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 ton…

Hello friends, in this post I make a dual bridge stereo amplifier, which can deliver up to 38W output per channel at 4Ω. For this amplifier, I use TDA7379 IC but you can use TDA7377 IC instead of TDA7379 IC. But if you use TDA737…

Hello Friends, In this post I make a 50W mono amplifier using TDA2030A IC and C4793 & A1837 Transistors, which can deliver up to 50W RMS output at 4Ω ±16V. The sound quality of this amplifier is very good. All frequencies are…
