So when I started to look around on "how to build a Serious Amp", I entered the universe of Gainclone amplifiers. I'm not an audiophile and not an expert on amplifiers either. More important, I'll also describe what I would do different if I had to do the project again. In this Instructable, I'll describe how I made the power supply and amplifier. It took me about 32 hours to build the amp and power supply. The power supply is based on a (way too large) 230VA toroid transformer. The amp is a so called Gainclone, using one LM3886 op-amp per channel. What you hear is far, far away from the real life experience. In the video, the sound is recorded with the on-camera mic. Even with my secondhand (€10,-) loudspeakers it sounds pretty nice. This amplifier is the best one I've ever owned (that claim isn't worth very much) and I'm really, really happy with it. The result is not a Perfect Amp, but it surely is a Serious One that is not that hard to build even if you never built one before. Oh boy, I am SO glad I did just that! If you find yourself dreaming about building an amplifier now and then, but are not sure about how to get it done: Read on! I described the making of my Serious Amp as good as possible, including the mistakes and successes. So I had the choice between buying a cheap receiver while knowing I had all the parts for a much better amp or just get started building it. I love to play music and the best sound system I had was my iMac. What helped me to get started is that I just needed an amplifier. ![]() In other words, I was just insecure about me as a maker of Serious Amplifiers. And I usually make stuff with electronics either for kids or as a "proof of concept", where accuracy and details matter only little. ![]() I know a thing or two about analog electronics and I can read and understand electronic diagrams, but I never made something from scratch that connects directly to a wall outlet. There was a gap between buying the parts and actually making the amplifier. Starting this project was daunting to me. It's my first "serious audio" project ever. I did it! I've always wanted to build my own amplifier, and now, finally, I made one.
