When applying your map in reality, I was fascinated by the loud and clear sound, and the shape was distinct and tidy. 👍👍👍👍👍👍👍👍👍👍💕

Yes. It's. I had the same impression when i lessened to it.the sound was verry clear. Thanks very much to made my diy amp 😋. You can also replace the two resistors for each channel with just one 8ohm 10w that will improve more the sound. Good luck ✌

Brilliant step by step including shipping or scavenging list too. Thank you,As a novice to electronics (I have assembled the digital clock kit and it worked first time😁) I feel confident in following your steps, would this amp be ok to use in a thodio type ammo can twin speaker box,can this amp be made with a wireless input and where would you best input the Bluetooth board signal leads?

@homemade_audio 2 жыл бұрын

Thank you for your comment, yes you can add bluetooth audio board and connect it to line in as shown on video to make wireless speaker.

I have to say its very impressive plus i like the simplicity of the amp might try to make this one, also what would be the estimated wattage putput for both speaker outputs?

trafo 12v and how many amps? How big is the fuse? Nice work!

Bel video! Mi piacerebbe provare a realizzare il tuo progetto, quali caratteristiche deve avere l'alimentatore da 12v? Al posto dell'attenuatore è possibile utilizzare un potenziometro logaritmico stereo da 10K?

@homemade_audio 2 жыл бұрын

Potenziometro 10k ok, per l'alimentatore 12v basteranno 2A per le prove, preferibilmente basato su un trasformatore migliore di quelli con commutazione.

Hello, can you tell me how many watts? Can you please make it with four negative transistors irfp250 and class A, and the circuit please be mono

grazie sei molto chiaro bel video, avrei una domanda vorrei far suonare un woofer in medio alto cosa devo usare? grazie

Ciao, grazie per il tuo commento, non posso offrirti una soluzione senza avere informazioni tecniche sul tuo midwoofer, per favore mandami il ref del driver oltre al tipo di progetto 2 o 3 vie, anche il ref del tweeter, altro dettaglio .

Genial !! Donc cet ampli est alimenter en 12 volts ? Est-il possible de faire le même avec une alimentation 220 volts ? Et que pourrait on ajouter pour lui donné plus de puissance ? Super boulot 👍

Avec 220v AC le montage va exploser 💣💣💣 ATTENTION il ne faut pas jouer avec de l'électricité ⛔️⛔️⛔️

When the output is by the capacitor, what for are these little coils?

@homemade_audio Жыл бұрын

it is to reduce high frequencies beyond 20 khz.

The simplicity of this project is enticing me to build it, however, I have very little knowledge of electronics. You will have to excuse me for my noob questions. What would be the RMS output per channel of this amplifier? In some of the components, you have mentioned 'audiophile grade'. Can I use non audiophile grade components of the same values? What can I use in place of the inductor coils? They are not available in my country. In place of the attenuator, can a potentiometer 10 kOhms 25 mW be used? Is it possible to connect potentiometers for controlling the bass, treble and balance, on this circuit? If so, how do I do ir? I have always wanted to build a Class A amplifier and this is probably the best chance that I will ever have. Much obliged for going through my entire post, any suggestions, instructions or advice will be appreciated. Thank you.

I made a class a 2 npn amp alot like rhis and i can get 8.5w rms out of it with a 18v 60w power brick and 2 100000uf caps

@napatencie4421 2 жыл бұрын

What for are theese little coils at the output? 🤔 Classic Common Emitter. This amplifier inverts the phase 180 degrees and therefore the speaker plus should be connected to the ground of the amplifier. Why is the output capacitor connected between the resistors instead of directly to the collector?

@homemade_audio 2 жыл бұрын

whatever the phase rotation has no impact on the sound of the speakers in normal wiring. the phase rotation of an amp is taken into consideration in the case of active biwiring where there are several amps with different phase rotations, in this case we do the phase correction by digital active filter and that's it is normal because even major amp manufacturers announce the phase rotation of their amps.

@homemade_audio 2 жыл бұрын

since the phase rotation of an amp is the same on both speaker outputs it has no impact on the sound because the two speakers remain synchronous.
