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…

Hello Friends, In this post I make a 50W mono bridge amplifier using TDA7265 IC, which can deliver up to 50W RMS output at 8Ω ±24V. The sound quality of this amplifier is very good. All frequencies are very clear. You can make th…

Hello Friends, In this post I make a 200W Stereo amplifier using TDA7294 IC, which can deliver up to 90W RMS output per channel at 4Ω ±35V. This is a flat frequency amplifier. So for that, all frequencies are very clear. You can …

Hello Friends, In this post I make a simple stereo amplifier using TDA2050A IC, which can deliver up to 30W output per channel at 4Ω with 0.5% distortion ±18V. The sound quality of this amplifier is balanced, and all frequencies …

Hello Friends, In this post I make a 100W mono amplifier using TDA7294 IC, which can deliver up to 90W RMS output at 4Ω ±30V. This is a flat frequency amplifier. So for that, all frequencies are very clear. You can hear all frequ…

Hello Friends, In this post I make a 500W class AB Driver. For 500W you need to use 5 pairs of 2SC5200 & 2SA1943 transistors and 45-0-45V To 50-0-50V 8A To 10A Transformer. Then I export the Gerber file (which you can downlo…
