Показать описание
This is a quick tutorial on how to build an easy low wattage amplifier using the LM386 OP AMP.

Feel free to join my electronics group on facebook too:

For this project you will need the following parts:
-A breadboard and cables
-The male end of a headphone jack
-A small speaker between 4 to 8 OHMs
-9 volt battery or power supply
-LM386 OP AMP
-220 uf electrolytic capacitor
-47 nf capacitor
-10 OHM resistor
-1000 uf electrolytic capacitor (this capacitor may not be needed if your amp is powered by a battery instead of a power supply)
-Some type of audio device such as a phone.

Can't wait until your next installments! It would be awesome if you could break down exactly what each component does as well! I know that resistors consume power and capacitors consume energy, but I fail to comprehend how exactly these along with the chip create an amp. Though I have been building pedals for quite some time, I still do not comprehend the "why" aspect of alot of what I am doing. You seem like a great teacher, and it would be super awesome if you could break this down further. Take care!

Sweet! Can u breakdown in the future each solid state devices role, kind of like you did with the 1000peco-ferad capacitor?

The supply voltage for the chip is 9v, what is the supply current, looking forward to your reply

Would this also work as a guitar amplifier?

Any advice for a printed parts list, I got a squirrel brain and would have to pause.the video and write it all down. Lol
