puedes hacer un transformador de 127V (el voltaje en México, busca el de tu país) a 9V usando un rectificador de onda completa. El hacerlo es más fácil que el circuito pero puede llegar a ser un poco más caro. Ya hecho identifica el positivo y la tierra y así conectas como viene en el vídeo solo que en vez de usar la pila pones tus cables que vienen de tu fuente ya transformada y rectificada. Sé que suena rebuscado si no sabes mucho de esto pero es muy fácil, te invito a qué busques cómo hacer un rectificador con diodos y capacitores y cómo usar un transformador (esos ya los venden hechos, solo cuida el orden de los cablecitos del segundo bobinado)
its rally worked properly but its about that 25k potentiometer its really hard to get one in my area do all connection properly and it will work. Don't worry its a good idea after all lm 386 is a amplifier on its own. thanks man nice idea. will you please show us a more powerfull amp. for guitar . waiting for a good reply :)
it rolls off high end before the signal is amplified, in turn making a louder amp before feed back. it is a good practice to have this cap, especially in high end audio, the lm386 is a low out put amp so many circuit omit it but it is best practice to have it. It does help keep excess noise out of the circuit. i hope that helps.
Hi! Nice, it's a kind of LitteGem? Since you have the gain pot at pins 1-8, no capacitor at pin 7 to avoid the noise amplified? Every time, it's a pleasure to see this amplifiers ;)
google "How to Read Circuit Diagrams" and problem fixed! if not, then call a buddy who does understand electronics 'cause it may not be your thing, bro. hope this helps. cheers!
@@ItAintMeBabe99 Turn your sound up. It was playing throughout the entire video. I have made many LM386 clean acoustic preamps and amps. I think the LM386 is well suited for this. You can add distortion/gain by tweaking the pot and or capacitors between pin 1 and 8 and get full on distortion.
I love that you listen all the components names clear and easy to read
And you even included a diagram
Very good job! Other TH-camrs don't do this
The volume pot on the input works much better.
All ground must be connected?
Can I use a potentiometer of 20k or more instead of 25? and can I use a power supply instead the battery?
You didn't gave information about Impedance as Guitar pickups do have high impedance in order of mega ohms but Lm386 have only 50 K input impedance?
No puede ir firecto a la toma de corriente?

Hi George
If I want the output for headphone
how should I do in this circuit ?
What should i change here if i am using 4 ohm 5 watts speakers?
sound test ?
Good 👍

thanks man nice idea.
will you please show us a more powerfull amp. for guitar .
waiting for a good reply :)
Good work...and nice idea bro
I have a quick question. Is the 1uf capacitor at the input necessary? Every ruby/NC LM386 amp doesnt have one so I'm not sure why its there

why does the signal enter through pin 2? datasheet specifies pin 3

lets stop with the lm386 stuff and use tda7052 like a big boy please
i'm bit confused does it beed preamp ? i think it does not work with passive
This is the preamp circuit afaik mate. The IC itself is an operational amplifier.
Show the working.. does it is good for acoustic guitar?
Yes, it is. You can check it out.
Muito legal, só faltou mostrar funcionando.
а конденсатор между 1 и 8 ставить что бы увеличить и не фонило
How do I ground
Explain in detail sir
This how we make a video
I did, not work
Eu fiz, não funciona
Thiam hle mai!!!
Play it, please
😂
Instruction not clear
You have a problem then, I understood clearly
google "How to Read Circuit Diagrams" and problem fixed! if not, then call a buddy who does understand electronics 'cause it may not be your thing, bro. hope this helps. cheers!
Should of demonstrated it, by playing the guitar.
