You probably dont give a damn but does someone know a way to log back into an Instagram account?? I stupidly forgot my password. I would appreciate any help you can give me.
That amplifier definitely works, no fake. I just built one half of it recently (mono) with a real MOSFET (Toshiba K2698), a BS170 source follower as input buffer (10MOhm input impedance), BS170 common source as voltage gain stage and a 2SC2240 emitter follower as output buffer to the powerstage. Works pretty well but 12V supply is just to less to get high output power. It distorts quite early.
I knew I was keeping those ancient PSUs for something!

Hey, yo lo hice y suena bien, pero hice modificaciones y con 24 volts, mueve unos parlantes de mini componentes, hay que disipar bien y colocarle su cooler fan... this amplifier have a good sound, thanks...
Can you elaborate please, are those 13007 really mosfets, or npn tranzistors? Because under that designation you have bipolar npn tranzistors (d13007k) and mosfets also (something like 13007-2). I found in my old power supply actually npn transistors d13007k in that place where you took yours transistors from board.
De cuantos watts es?. Mejor saldría un amplificador con esos MOSFET o sería mejor usar un integrado como el TDA7377?.?????. Cuál de los dos daria mejor resultado?.
Great thanks. I am really impressed by your interesting suggestion. I have some KSC5020, 2SC1815 and F20N50, 2SC1384 now. Can I use them instead of 13007, C945? Or should I change some parts of your circuit to use them?
@@ShareTechCreative no, you don't understand me. I mean, in the video you say "take the two 13007 power MosFETs..." And later you refer with B, C and E to the pins. So see, a MosFet has no B, C, E but G, D, S. But the 13007 is BJT so B, C, E is correct. But MosFet is not. Have a nice day
@@bertr6741 Just what I said, didn't I? Please look at my above answer to him. He writes in the video "take the two 13007 power MosFETs" which is wrong because 13007 is s BJT
You can use 18 volts on 13007 transistors, but you may have to change the voltage divider for C458 transistors since they are operating in 12 volts. Good luck

Hello Friend how are you? . your videos are very good. since I don't know much about transistors .. Which of all the videos and projects provides the best sound quality? I have a woofer and speakers - 12v transformer and also a PC power supply but what interests me the most is a good faithful quality of the sound. I saw all your videos and I can't decide. maybe you can answer me, greetings .. from Argentina
"How to make STEREO amplifiers with ATX PC power parts | Class A" I'm still wondering where the fuck he got those white blocks.. Surely, not inside the ATX!
@@gwantweng enough for desktop speaker. edit: class A amp has efficiency about 50%. instead 10 watt/ch or 20 watt total which need 100 % efficiency from Bench PSU reading ~1.5 amp x 12 volt = ~ 18 watt. You only get half of that since the design is Class A. Which is about 5 watt / channel.
All that is fine but those resitors waste energy on heat too much , can be replaced with 12V/ 5 or 10W bulbs it would be better to use parts and build AB class amp or make class A as JHL69 amplifer on 12 or 24 V
@@TerryGrancho isn't better to waste that energy in audio output power instead just heat ? its not expensive obviously, but the performance is sooo poor

Bác ơi sao e làm như sơ đồ nhưng con trở 10w10ohm nguồn dương nó nóng hỗn lắm mà mạch k hoạt động. Mình ktra lại chỗ nào bác
Bạn kiểm tra lại transistor C945 xem chân B nằm bìa hay nằm ở giữa. Chân B nằm bìa mới dúng nhé!

Se puede usar 8 ohms en speaker? Tengo unos de tv
Yes, you can use speakers from 4 ohms to 16 ohms
Excellent !!! Interesting design ! Very nice to repurpose the old parts ! Thank you for sharing !
Many thanks!
BIEN EXPLICADO MASTER, EXCELENTE APORTE, GRACIAS...
Thanks
13007 is just an NPN Switching transistor , not a MOSFET...
Mạch thật tuyệt. mình cũng mê chế loa
nice work bro. thanks
Welcome 👍
Amigo assim fica difícil, onde foi q vc viu esse resistores as 10R/19w na fonte ATX.
How could I change this to 2.1 ?

Hello friend excellent video .my question goes .how to do to generate volume increase to a device that can not be increased volume?
De cuantos watts es?.

Buen video y proyecto. Pero resultó ser de unos 3W. El sonido es bueno. La resistencias de 10W y los 13007 necesitan un muy buen disipador de calor.
Osea pajaass
Muy bueno excelente proyecto ahora hace amplificador de audio sacado de televisión
Thanks
Bro good job .Can this circuit be made more powerful, for example by increasing the number of transistors?
Yes you can
@@ShareTechCreative thanks bro.When we use more transistors, how will we make the circuit connection?
VERY GOOD PROJECT !!! EXCELLENT CLASS "A" AMPLIFIER
Many thanks!
Excellent video, you can make a preamp for electric guitar or bass
for this amplifier
Cool idea!
Hi, how do you calculate the value of the resistors (33k and 10r/10w) what if I use a different (more or less watts) power supply components?
These are the ultimate ingredients, cannot be truncated, and cannot be altered!
I think you can basically use what the power supply comes with. Except the high watt ceramic resistors which he probably got from a amplifier
Excelente video la única duda es la potencia de salida del amplificador y las bocinas que se deben colocar en Watts y en ohms
De casualidad ahora sabes la respuesta?
The 10 ohms resistor have to be 10 watts or any watts serves on place, and what the purpose of they
god job ! but 12v dc input cables ! you need more biger and powerful cable... Class A amp need amper
Thanks for all
Dude are you sure those 13007 are mosfets? On electric sheme you provided in video stands bipolar transistors!
Hola.
puedo aumetar a 24volts la alimentacion ,solo subiendo el voltaje de los 4 capacitores ?
Could you please show me B, C and E leads at a FET transistor? I bet you won't find them...

how much wattage can carry for that amplifier?
What is the output power

@@Davidslabofficial I bet those ATX are the best in market! All the resistors I found are rice-like things... 🤦🏻♂️

Más de 10 vatios por canal
it's about 10W rms /channel amp from a PC part :D nice job
Yes, thanks
@@ShareTechCreative to small watt
@@gwantweng enough for desktop speaker.
edit: class A amp has efficiency about 50%. instead 10 watt/ch or 20 watt total which need 100 % efficiency from Bench PSU reading ~1.5 amp x 12 volt = ~ 18 watt.
You only get half of that since the design is Class A. Which is about 5 watt / channel.
why did you not use a desolder station instead
the resistances can also be:
- 0.47r . 1w
-10k .... 1w ..???
All that is fine but those resitors waste energy on heat too much , can be replaced with 12V/ 5 or 10W bulbs
