Email me new tutorials and very occasional promotional stuff: In the rest everything is equal to the circuit. The means to do so have been provided.

Also, some airflow spacing is needed around the caps. So the question is, if and how much would adding fans to near the circuit affect sound quality? Love the in depth circuit analysis on components functions and why values were selected. The resistor reduces this current and breaks the ground loop. Probably 1 volt too? Judah on October 4, at If I am correct the pcb layout needs to be modified to represent the difference in size between the 50pf and the pf.

The board layout has allowed for flexibility which will allow for experimenting with components. However If amp is run at near full load not likely heating effects of the transformer and bulk storage caps should be cooled as well. If a separate supply is provided for each channel with separate capacitors bank for each channel, or even possibly with two power transformershow should grounding be organized?

I enjoyed every moment of the explanation, Great work and thank you for sharing Reply. Use low ESR bulk storage caps and minimize inductance lengths. A bit much perhaps? And I have a few questions: The formula to use is:.

I can use it, no? Bob Pendergast on April 3, at dxtasheet Brian Stover on January 28, at Could you please add a print stylesheet to the website, where all the unnecessary stuff navigation, newsletter subsciption, social links, footer, etc is hidden and the content column has full width? I think this is an omission in the article. Depending on the rectifier and diodes used, this should be anywhere from 1.

Hellothis is a real complete guide for building a high quality amplifier. I then switched to a 3 amp Slo Blo and every thing works fine.

Dave on October 30, at 8: And I have a few questions:. MBBS on October 15, at I have a question though. I have a transformer that feeds 22V at 7A.

A Complete Guide to Design and Build a Hi-Fi LM3886 Amplifier

John on August 15, at 3: As an electrical engineering student, I love getting the chance to truly understand the process dataseet creating the design. I would not call this basics. I have just a question: Firstlyif we want a volume control for this amplifier, how we will achieve it? Talk to you next timeā€¦.

With the right layout and component selection, you can build an excellent sounding Hi-Fi audio amplifier that will rival high-end amps retailing for several thousand dollars or more. Pietro Di Zinno on April 3, at 1: The power supply and each of the individual components do have a massive influence, especially as there are so few of them.

This is an Excel spreadsheet that calculates output power, heat sink size, gain, llm3886tf other useful parameters:. Im considering building the amp, but i have a question that i sadly havent found an asnwer to. Maybe it helps other people with similar questions.

Use the metal tab version of the part. Thanks a million for the detailed top quality guidance. Any idea what it can be?
