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 make a 3 band mono tone control in this post. For this tone control, I have used NE5532 IC. But in place of NE5532 IC, you can also use TL072 or 4558D IC. You can control the high, mid, and low frequencies in thi…

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