Hello Friends, in this post I made a flat frequency Stereo amplifier, which can deliver up to 68W output per channel at 4Ω. For this amplifier, I use LM3886 IC. This IC is specially designed for active studio monitors, for its …

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 made a mid-pass filter. You can use this mid-pass filter with any amplifier. For this preamplifier, I have used NE5532 IC. But in place of NE5532 IC, you can also use TL072 or 4558D IC. In this low…

Hello Friends, in this post I make a low-pass filter. You can use this low-pass filter with any amplifier. For this low-pass filter, I have used NE5532 IC. But in place of NE5532 IC, you can also use TL072 or 4558D IC. In this lo…

Hello Friends, In this post, I made a 25+25W stereo amplifier using the TDA7265 IC, which can deliver up to 25W RMS output per channel at 8Ω ±24V. The sound quality of this amplifier is very good. All frequencies are very clear. …

Hello Friends, I make a 100W subwoofer amplifier in this post using 2SC5200 and 2SA1943 Transistors, which can deliver up to 100W RMS output at 4Ω ±30V. For the low-pass filter of this amplifier, I have used the 4558D IC. This is…

Hello Friends, I made an output balance preamplifier in this post. For this preamplifier, I have used NE5532 IC. But in place of NE5532 IC, you can also use TL072 or 4558D IC.  For designing my PCB, I used EasyEda online software…

Hello Friends, I made an input balance preamplifier in this post. For this preamplifier, I have used NE5532 IC. But in place of NE5532 IC, you can also use TL072 or 4558D IC.  For designing my PCB, I used EasyEda online software.…
