What is it?

This is a bare PCB for DIY high quality audio amplifier based on TI/NSC LM3886 or LM2876 chips. It supports both through hole and SMD capacitors.

Why did you make it?

There are ov the market PCB's for DIY audio amplifiers based on LM3886 chip, but practically all of them require dual supply. Sometimes for the electronic freak is difficult to find the right transformer having two secondary windings and such transformers cost a lot of money. Using the offered PCB can be assembled an audio amplifier, which works on a single supply. 20 V AC/DC power adapter is enough for supplying of audio amplifier based on the LM2876 chip and its performance is spectacular.

What makes it special?

Based on this PCB a high quality audio amplifier working with single supply can be done. It supports both through hole and SMD capacitors. A switch or relay for "Mute" control can be connected to the PCB, making the project more flexible Now the PCB's are available in blue colour.

Ok

The quality of the PCB is good, but the design is poor, really not professional. some components are under big capacitor, some holes are too small
Do the job for a simple audio amplifier, it's ok anyway for the price.
just one point the shipping cost is double for two pieces ! surprising

VERY high quality product, and a superb seller!!

I'm somewhere between a beginner and an intermediate electronics 'tinkerer', and ordered some LM2876 amplifier IC's from Texas Instruments to "build my own amplifier". Once I had the IC's in hand, I realized that it was going to be a little more involved than building an amplifier based on the LM386, so I began my research. I found several circuit diagrams and examples others had built but was still not quite confident in my ability to properly complete this project.
I found these boards and realized this was EXACTLY what I needed to make this project a reality. I exchanged several emails with the seller (Chichomecho) a month before I ever placed my order and, although there is a 6-hour time difference between us (I'm near Atlanta, GA in the U.S. and the seller is near Zürich, Switzerland) and wasn't even a customer yet, he always responded very promptly and gave me very detailed answers to my questions. I ordered 4 of these boards and continued to ask questions via email. I'm sure that some of my questions were "beginner" questions, but "Chichomecho" answered every question, provided me with circuit diagrams and photos of completed projects, and explained many things that I needed to consider for this build. Although he was just returning from vacation when I placed my order, I had all 4 of them in my hand, in PERFECT condition, in just 1 week. Did I mention these came from Switzerland to the U.S.?
These boards are indeed VERY high quality and I have NO doubt that they will outlast all of the other components I'm using in this amplifier build. I cannot overemphasize how impressed I have been with this seller, his product, and this process. I would not hesitate, not for one single moment, to recommend EVERYONE purchase with confidence from Chichomecho. Thanks!
