Worth mentioning this is a _class A_ amplifier. It will pas considerable DC current (both through the transistors and speakers) and will dissipate quite a lot of heat even with no signal. As its class A with no degenerative feedback, it will also be non-linear as well as being a current amplifier. Good for educational purposes especially if you can probe it to see how it works, but it will get extremely hot in short order and potentially damage your loudspeaker as well if its not sufficiently rated owing to the large (~1A) DC current that will circulate even without any input, so user beware.

[@johnnyboy2459]

Its also Mono? Is he sending both channels into 1?

[@mysock351C]

@@johnnyboy2459 It looks it. Basically the transistors are hooked in parallel with ballast resistors.

It looks like the 470 uF electrolytic is wired + to transistors, and -- to the potentiometer (wiper pin 2) I didn't see anything mentioning that and it could be important. Otherwise very clear and pretty cool, straightforward, fun easy project.

Cuidado !! Si los voltios que exitan las bases es mayor a 0.5 vol, circulará corriente continua en los parlantes y se pueden quemar, la resistencia de 1kohm tiene que ver en eso.

all those components are from an atx power supply?

[@stefanstanciu9896]

how about you use heat pads under the transistors not to cancel eachother out by short on the heatsink? with no pads you have the big steady "negative shine" that heats up the speakers. and you may want a 2 k resistor, lower output but longer life

[@user-hv5tx6qv7k]

how with this circuit did you get rid of the constant voltage at the output? in an amplifier it is very important not to have a constant voltage at the output. constant voltage heats up the coil even if no sound is coming out.

[@FM_PERON2022]

Yeah, you're right, in the description says it's not for continuous use, since it has a high dc output (I think that's the meaning of DCO)

[@TheImagem7]

O segredo está na fonte, que acaba limitando a corrente, em 2A, pois se aplicar uma fonte de maior corrente, o circuito vai drenar mais corrente aos altofalantes, que por estarem em paralelo, podemos supor 2ohm, constituindo uma carga de baixa impedância, vai levar em saturação, com queima dos transistores. A potência maxima deste arranjo, é de 5 watts RMS. Com baixa eficiência....

What is "DCO" ? How many W this project?

[@RodrigoFlrSouza]

It means a good amplifier or "professional" does not delivery in the output DC current only AC, this project delivery DC + AC in the output it will cause heat in the speaker, they are made to work only with AC signals

[@riotintomaršsadrine]

(D)irect (C)urrent (O)utput

[@jasonsangwin4006]

DCO is "DC Offset", the author is warning that the DC Offset is high in this design. Basically, in an ideal case, there is 0 DC Offset, meaning 0 DC voltage when the amplifier is idle. For a Speaker to work, the output is AC (Alternating Current) and the alternating current flow is what causes the speaker to push inwards and outwards. If you apply DC (Direct Current) the speaker will not move ... rather it will move into position once and stay there until you open the circuit, in which case it will come to its rest position in the middle. This is because with DC, the current only travels in one direction ... so the voice coil will also only travel in 1 direction. Also the DC voltage will be reached and remain constant, which means the speaker will also reach a position and stay there and not move. The idea is that if you put a speaker on the table, it is in a rest position. This "rest position" is when the speaker is receiving 0V or disconnected and just sitting there. Same thing. Given the intended circuit is an AC (Alternating Circuit), which makes the speaker move inward and outward, the rest position is at 0V. If there is a bit of stray DC voltage across the amplifier's speaker outputs, what it means is there is an underlying DC voltage that is different to 0V which means that the speaker never comes to it's 0V rest position while connected to the amplifier. The rest position of the speaker is "Offset" from the normal 0V position due to the DC Voltage ... so "DC Offset" (DCO). The speaker never comes to rest basically, it is offset but this also has a thermal implication. The voice coil will generate heat as current is passed through it, the inward and outward movement of the voice coil acts to keep the voice coil cooler. As DC results in current passing through the voice coil but the voice coil not moving, it will not cool itself and is more prone to overheating and causing damage. Everybody has a similar idea as to how much DC Offset they can tolerate, be it 100mV or 25mV but you really don't want to see more than 100mVDC on the outputs.
