"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!

[@Davidslabofficial]

Those are 10watts 10ohm resistors and lol yes they are not inside that Atx 🤣

god job ! but 12v dc input cables ! you need more biger and powerful cable... Class A amp need amper

Thanks for all

[@PacemoiArdrokeCas]

The 10 ohms resistor have to be 10 watts or any watts serves on place, and what the purpose of they

[@branislavcolic9099]

Dude are you sure those 13007 are mosfets? On electric sheme you provided in video stands bipolar transistors!

[@branislavcolic9099]

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.

[@elektronikhobim6903]

13007 npn transistor

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?.

[@sebastianyvn9635]

From where u take 10w 10r resistor?

[@everaldombarbosa1478]

hello friend do you have any video on how to make an amplifier using tda 7264 since already thank you

[@zlatkovidlanovic6454]

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

[@thomasr.5443]

Could you please show me B, C and E leads at a FET transistor? I bet you won't find them... By the way, 13007 is a BJT, not a FET

[@ShareTechCreative]

You see in the description the video

[@thomasr.5443]

@@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]

13007 is just n NPN switching transistor.. not a MOSFET...

[@thomasr.5443]

[@TerryGrancho]

Para qué quieres ver como se conecta, todo lo va explicando en el texto amarillo en el mismo video...

[@thomasr.5443]

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.

[@era7928]

@@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.

@@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

[@Postpunk333]

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

[@TerryGrancho]

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?

[@ShareTechCreative]

These are the ultimate ingredients, cannot be truncated, and cannot be altered!

[@joshr.4398]

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

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
