Could you also consider doing a solid state discrete power amp with dual dc power supply. The power supply and each of the individual components do have a massive influence, especially as there are so few of them.

The means to do so have been provided. You seem to know what you are doing as well as having a lot of experience.

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

Bob Pendergast on April 3, at I ordered exactly the chassis and heatsink as specified and there is no way that the heatsink will fit in that chassis. George on October 4, at 3: A bit much perhaps? If I may offer my observations, which are purely subjective though based and lm3886tv doubt influenced by research The power supply and each of the individual components do have a massive influence, especially as there are so few of them.

Thank you for this really great article. Where would i put in a stereo potentiometer for volume control Reply. High current grounds are the ground feeds to the power supply decoupling capacitors, the Zobel network, and the speakers.



The components on the PCB layout match the schematic above. Buy a bigger case.

The main system ground is located as close as possible the reservoir capacitors on the power supply. Is there are substitte that can be used? Lj3886tf on December 21, at 5: First off — thank you for the great tutorial and the breakdown of each step.

Thomas on Darasheet 28, at 1: 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. I just finished my build based on your tutorial, with minor changes. The power ground and signal ground are the only ground networks on the PCB. All other 47 pages of the article and the comments are hidden. Or is it just because the part is only manufactured like that by Mundorf?

Liwei Sheng on June 7, at 4: Cant wait to see post on power supply! I found the post about LM amplifier. I also really like how you supplied the calculations for determining the size of the components. I am asking for information by email desoto wp.

First being to place fuse at bridge input, which will protect all power supply components. As C13 is used to stabilize the amplifier Lm3868tf would just like confirmation that the parts list and silkscreen are correct. Mohammad fahmawi on September 17, at 4: Vince on February 7, at From my understanding re: Good luck, Ed Reply.


Please double check dxtasheet information below, as I do not have alot of knowledge about electronics yet I am a newbie.

I am having a hard time finding X7R Ceramic resistors. The is in fact the ln3886tf, the 47pF is the bigger one! However I am almost a new graduate of Electrical Engineer and not sure if I can handle the processes.

Talk to you next time…. Francois on October 11, at 9: Success with the build, Ed. In the rest everything is equal to the circuit.

Heat sinks for Natural Convection should be exposed to room air flow. So depending on the capacitor supplier used, the design may have larger bulk capacitance, divided into multiple smaller caps in parallel as needed that can satisfy the RMS ripple requirement.

Success with the build, Ed Reply.

Thanks for the help! I do not care particular brands of capacitors or any other components as long as their specs meet requirements. The board layout has allowed for flexibility which will allow for experimenting with components. The highs are datsaheet, but not harsh at all.
