@@jacquesb5248 well, no. I can see no pulse wave generator, so class D is out! Since it is only one transistor (NPN) per channel and I don't see any biasing, it is definitely class A with 65% heating the room.
cant you hear the terrible clipping when any deeper bass plays ? That' s coz he is using collector feedback resistor for biasing. Very unstable and impredictable with temperature changes.

This is only a half wave (simple) amp... As your power supply is only 0 to +12V, only the positive section of the audio will pass. The negative will not. Audio has both. You would either need another set of BJT and a 0 to -12V supply (push-pull/class AB) or a voltage divider to add around 6V to the input so both halves of the signal could be amplified (class A).
ola meu amigos....montei o circuito com 4 transistores 13007 e coloquei como pré um amplificador de caixa de som de pc com tda2822 e o resultado foi muito....e pode ligar junto aos 12v pois o tda2822 suporta ate 15volts e tbm alimentei todos os circuitos com uma fonte de pc.....show
Yinede transistör seçimi doğru bir seçim değil ayrıca amplifikatör yaparken npn ve pnp şeklinde seçilirse eğer birbirini tamamlar bu doğru bir yaklaşım değil ses transistörü olarak toshiba c5198 daha uygun olurdu sonuçta ses için geliştirilmiş transistör özetle 2SC5198npn ve 2SA1943pnp birlikte kullanılırsa eger dengeli bir şey yapılmış olur, videoda kullanılan transistör daha çok güç kaynakları için uygun olacaktır

It would just be a process of adding resistors on the input from the aux to limit the frequency down to 60hz and below, maybe a little bit higher than that but you get the point
Hello, Sir, I have two questions, please: 1. Could you please give us more data about those coils? 2. What's the purpose of controlling each channel volume separately? Thanks in advance. Regards.
This is a pretty cool demonstration of how simple an amplifier can be. But it’s really not very useful. First, it’s low gain. Most transistor amplifiers have a voltage gain stage as standard transistors are limited to gain of about ten to one. Second, this is a class A amplifier which means that the transistors are always on, sucking current and making heat. Third, the input impedance is very low which taxes the input source. I would be very careful plugging an expensive smartphone into this amp and trying to crank the volume. Having said all that, it is an impressive demonstration of minimalism and an analysis of the circuit would make a good basic amplifier tutorial.

An excellent example of how a REAL MAN'S PTP amplifier is made. So what if there's no circuit overload protection on the amplifier itself. Personally I don't even need potentiometers, only an on/off switch. As for "protection" circuits, build it (or them) either in combination with or separate to the amplifier as a PTP circuit and most importantly build it right.... Well done mate, clean and clear professionally planned and executed build.. Keep up the good work. I will build another like this myself once my valve monster is reborn.. >8-D
I think he thought that because he connected the same power to both transistors, they would emit a single signal, this would be true if base, collector and emitter were all interconnected, which is not the case.
Of course these speakers would have to be correctly mounted to prevent back radiation from mixing with front to prevent phase cancellation. Need more info on the toroidal coils such as wire thickness and amount of wire turns. Good video, Thanx

It's not a class A or a class D, it's a dumb amplifier which supply continuous dc to the speaker, your speaker will burn soon if you use this
If you want to build a small amp just use LA4440 ic for single supply or TDA2030 for dual supply
Если это класс А, то неплохой нагреватель получился :)

класс А должен быть мощный резистор в цепи коллектора,который делит напряжение пополам

Won't this circuit put quite a bit of DC across the speakers?
it will
I certainly won't put that POS on my speakers!
1:43, He failed to mention the gauge of the copper wire, the resistance of those coils, and their Henries. Mention them urgently.
Spoon feed?
The value is actualy not very important. Judging by the looks it will be sth around a few hundred uH
The inductor also makes no sense.
