A Complete Guide to Design and Build a Hi-Fi LM3886 Amplifier
Martin Arh on March 6, at 2: I made an amp with LM in And be sure to like, share, and subscribe if you found this helpful! The video at the beginning of the post will give you an idea of what it sounds like. It is hard to resist from building this amp: Could you also consider doing a solid state discrete power amp with dual dc power supply.
The components on the PCB layout match the schematic above. Judah on October 4, at I think the sound my LM amp produces is much sweeter and softer than my Yamaha.
Success with the build, Ed. Thank you for your excellent work on this guide. Hi, I really enjoyed reading this!
Robert on July 21, at 9: Use two smaller transformers and put bridge and caps on amplifier board. You explained it very well to me! John on August 25, at 1: Im considering building the amp, but i have a question that i sadly havent found an asnwer to. Hi all my 51pf silver mica is definitely much smaller than the pf silver mica I have so….?
The main system ground is located as close as possible the reservoir capacitors on the power supply. The PCB has 2 holes for the diodes, but the parts list specifies a 3 pin diode.

I used single sided PCB, but tried sticking to your layout as closely as possible and changed some l3m886tf — especially the Mundorfs for something readily available and a bit cheaper. Thanks for the help! You explain in the tutorial and as the actual photo of the cap shows the actual value of the polypropylene is. Thanks for your reply, Robin!
The TF version is isolated and mounts directly to the heat sink. Also, at the same time provide IC centric decoupling of the supply.

Victor Faucheret on April 22, at 5: If I am correct the datashedt layout needs to be modified to represent lmm3886tf difference in size between the 50pf and the pf. The sound is fantastic, however I can not reach it but the power is far from expected. Francois on October 11, at 9: At high frequencies, the impedance of C sn is very low, so high frequency current is shorted to ground.
The main system ground connects to the ground protection circuit discussed belowwhich then connects to the chassis.
I have a question though. Overture Application Note AN Package is still on ship. Could you update this info.
Jeffery Lockmiller on November 7, at 5: In order to bring this down to a more reasonable level, I decided on using 4. Circuit Basics on April 1, at 2:
