I wanted to build this project a long time ago but I have no time to do it. Today I decide to make a PCB design for it. Unfortunately I do not have any time to make the actual prototype. I will post my design so that anyone can build their own prototype.Continue reading “500W Amplifier from Eliot Sound Products”
If you love to build audio amplifier then you must be familiar with 2SC5200 and 2SA1943 power transistors. They are one of the most used power transistors for power audio amplifiers. While looking for a next project, I found this simple layout on the internet so I decided to make my own version with some few improvements.Continue reading “2SC5200 2SA1943 Simple Amplifier”
Here’s a simple amplifier you can build. it uses the popular TDA2030 amplifier IC. It can deliver up to 35W which is good enough for room audio. It is in bridged mode meaning it is using 2 IC with the output of the other IC is 180° out of phase.Continue reading “TDA2030 35W Bridged amplifier”
Here’s a simple guitar headphone guitar amplifier project that you can use for practicing. The headphone amplifier uses a LM386 that can be able output up to 0.7W than can be use also for small speakers. It also has an auxiliary input that can be used to connect your phone or an MP3 player for you to jam and play along with the song you are playing. It has a simple built-in overdrive channel.
