Parabéns pela montagem ótimo
Excellent..seems so simple.. I will try to make this circuit definitely, soon as I find time after work..but for a little bit different usage, for electric guitar amplifier :-)
Thank you so much friend
Excelente, Felicitaciones y Gracias
Thanks my friend
Brother everything is fine I give 5v its working awesome don't worry no vibrating sound
Brother thanks for your information I also thank you for trying this circuit😃😃😃😃😃😃😃😃😃😃😃
Buen video.Conseguire' los componentes y lo hare'.Muchas gracias.Bendiciones.
Very very thankyou brother
You have cleared my doubts make more videos brother
Brother thanks 😃 I make more vedios 😃😃😃
Brother you can ask any questions any time I anwser your all questions.
Brother watch my new vedio Top 5 projects using D718 😃😃😃😃😃
Wow! Nice work.
Thank you so much friend for your support
I try to make this amplifier wow its work the sound is clear nice i'm happy
thank you so so so much friend I am very happy thanks friend for try this circuit
شكراً جزيلاً. ..
Thanks friend
Sajetion to you :-
1)voltage input 12 volt. 2)spiker connection transistor middle point ke sath ek spiker wire jordo or 1k resistor ke sath ek wire jordo spiker wire or 1k resistor jahaper jor gaya bo ho gaya 12 plus input.
Nice idea thanks friend
Brother I want to add potentiometer as volume control so could you give me a suggestions 50k or 100k or 10k
100 K potentiometer is best because it control volume very down to high
@@creativechannelpro371 where to connect the potentiometer
i used three d718 3 per channel power supply for that 12 v can u tell me how many amps
WOW Friend Nice idea ( 1.5 to 6 amp) is better)
Brother 100k potentiometer not working
And when I on this amplifier there is a vibrate sound in background what I have to do to remove that vibration sound
I use headphone cable L+R together and 1 ground
Brother check your Audio in Cable may be this cause the speaker vibrating Brother what happen if you plug input cable in mobile its work or not tell me😯😯😯😯😯
Brother how you connect potentimeter
👍👍
Thanks
Brother I used 3pin potentio metre but it did not worked so I removed it and directrly connected it as you show
Sorry brother 6 pin potentiometer works in this amp😦
Brother I used 1 transistor and 2×30w speaker in one transister. Is it cause any problem
Bro some time TH-cam notify comment sorry thanks for watching my vedio yes you can usr
Hi.. that is great :D .. sorry for my english, I have B778 and D998 can I use them? I have a potenciometer 3B50khomx2 and can I use 12v? or only 5? Thanks :D ...
Dear brother these transistor are not for amplifier purpose sorry
Brother could you help me to remove that vibration .
It's working very good but it has unwanted vibration
I want to remove it
Brother your power tell me your power supply volt and amps
Try different values capacitors 1000uf capactors is not recommend you can use 220uf to 1000uf
10v 2 or 3 amp
Bro pls try 5volt 2a first
i tried this and it heats up my speaker. I use 12V DC 1 Amp power supply and i already tried with 5 volt 2 amp but the 12 Volt DC seems to give more louder sound without hurting the power supply. But for some reasons, it heats the speaker
Use heavy watt speaker
Thank you so much for comment
Cấp điện nguồn loa có bị hút vào hoặc đẩy ra không bạn?
Thanks for comment friend can you explain me in english
Sir can i use TIP147 transistor in this circuit? Or need to change capacitor and resistor value? Pls answer. Thanks
I also have BUZ11 mosfet. Can i also use this to your circuit?
Yes bro I think you can use tip147 PNP transistor you can change the input negative and positive terminals and no need to change any other components Thanks for Comment friend😊😊😊
Friend I think MOSFET cannot work
@@creativechannelpro371 thank you so much sir for the quick reply. One more thing. Can i change capacitor value to 2200uf/16v? If possible because 1000uf/16v not available. Im onboard cargo ship my components are limited. Many thanks again sir.
freind 1000 uf is suitable for this amplifier I think 2200 uf give so much unclear voice or may be It will not work sorry I don't try
B688 or D718 ko jyada se jyada kitna volt par chala sakte he???
40 0 40 par chalega????
nahi burn hojay ga
Brother before I pulg audio pin into mobile and after I plug into mobile and while playing song and before playing song also this vibrating sound happening when I on the switch of this amplifier it is happening same as while playing
Brother check your resisters values
Brother in stereo amplifier only 6 pin potentiometer work
1k ohm half watt
Brother check your heatsink it may be conductive if conductive use imulsion paper
Check heatsink it may conductive if conductive use imulsion paper
Hi bro nice video...I have disparted a lcd can you there is alot of transistor how can i know which one works for amplifire?
Thank you so much bro dear bro LCDs not have a amplifier transisters because lcds have a ICS powered amplifier. I get these transister from dead amplifier box
@@creativechannelpro371 ooops thanks alot i saw alot of video about making ampilifire they have used different kind of transistors. Would you tell me all type of transistors usable amplifier which one is the best?
Tc5200
Is best
D718
B688
Tip41c
Tip42
C3180
Bro if you want to make amplifier with common transistor like C1815 and A1015 please watch my vedio
th-cam.com/video/xB1dfKiRozI/w-d-xo.html
Is that just a normal paper or special kind where can i find it please?
Bro I used normal paper
Que murrinha de ferro de solda é essa??? Vôte colópia!!!!
Friend pls explain me in english
@@creativechannelpro371 he was just commenting about your soldering iron, and that he will make a copy of it. I guess, who knows what colopia means lol.
Thanks friend for your Translating Yes friend many friends insult my innocent soldering iron.
Please replace the capacitor 47uf25v the sound is good distortion free
Thanks my friend Great idea
Brother can i use 12v power supply and 2×30w speakers ?
Is it possible ?
Yes brother you right and genius you can use 12 volt Supply but not for Very long time use otherwise transisters will blown and yes you can use 30w Speaker also
Thanks for comment brother😃😃😃😃
If you have any questions you can ask freely
Brother I also try to make more powerful Stereo amplifier with 2 D718 this vedio amplifier is not too powerfull I upload vedio on next week 😃😃😃😃
Brother if I use 10v power supply and 30w 4ohm speaker will these transistors blow
In 220 volts plug,it s ok?
Thanks for comment friend
you need a DC power supply at least 5volt to 12volts
Thus ist verry siple
Thank you so much friend
Klau pakai tr finalny 2955 dan 3055 bisa gk bos.. pengen cb nih.
Thanks for Comment Friend I don,t have the Transister 3055 and 2955
@@creativechannelpro371oh..
If have tr final .cant make amplifier as this vidio. Tr 2955 and 3055.
OK friend 😦😮☺
amigo de cuantos watts es el amplificador
Bro can you translate in English
@@creativechannelpro371 friend of how many watts is the amplifier
At least 5W I think bro not confirm sorry for that
Can I use 4 ohms5 watts speakers ?
Yes bro can but use on low input voltage
what kind of low input voltage cant use 12v??
Brother I reduced to 9 v now the vibration was reduced but very very little it is happening
Brother I think this amplifier is best on 5volt 😃😃
Como se llama la musica de fondo
Thanks for comment friend the song name is
Wariyyo mortal ncs
song name please of the video thank you.
Warriyo mortal ncs
If i use 12v it is ok sir?
No bro 5-6 volts are good 12 volt heating a transistors and audio distortion
Where do you life ,freand ?
Iam in life jkrta. Do you speacking in indonesia..??
Sorry for too late reply TH-cam not show me some comments I can speak English and Hindi thanks for watching vedio
chevere , yo lo hice pero uno suena fuerte y el otro menos - por que
Thanks for Comment Friend may Problem in circut or your speakers is not same
@@creativechannelpro371 Entonces...... Según tu circuito ¿Cuantos amperios entrega? ........... solo especificaste que 8 ohmios
Friend I only understand English language can you please explain me in english
@@creativechannelpro371 I just want to know, how many amps does the circuit you designed deliver?
In the description and 03:43 video, you only mention that: you use two 8 ohm speakers (so as not to make a mistake as the friend above).
#JoseGeovannyTorres Recuerda que ambos parlantes deben tener la misma cantidad de ohmios y watts (c/u) para que la división de corriente sea equitativo para un solo circuito. Si usas un parlante con mas watts y ohm en el mismo circuito
Esse gosta de fazer e ensinar
Thanks for comment friend can you explain me in english
@@creativechannelpro371 😄
😆😆😊😊
THANKS FOR comment you are right i translate your language portaguse
cuanta wat de salida da
Bro i want to answer your your question plz tell me in English
Bisa pake aki 12v bang???
Bro english I can understand thanks for your comment ❤️❤️❤️
Watts is? 50w
Sorry friend I think 10-15 watt not confirm Thanks for comment
