Esse circuito tem no mácimo 6 watts a julgar pela complexidade do circuito, a falta de um pré amplificador e a baixa tensão de trabalho. Para um amplificador de 100 watts você precisa de pelomenos 28 voltz de saída em 4 ohms SEM DISTORCER o som. E com a tensão máxima para esses transistores você terá 80 watts com a capacidade máxima do transistor e ele torrando de calor e porfavor NÃO minta, pois se alguem procurar um amplificador de alta potência para uma caixa amplificada ou montegem e venda você chamará a atenção para algo que nem 10 watts tem. Obrigado!
Emitter follower resistors would be a good idea, otherwise, the transistor with the lowest base-emitter voltage drop will dissipate all the power, without turning on the other transistors. However, with this circuit, one transistor, dissipating 9 watts of power is well within the 80 watt rating of the transistor that does carry the load. 6 or 7 volts at 1.5 amps is well within the safe operating area of a single transistor. This amplifier dissipates 9 watts of power, producing 6.3 watts RMS, based on a 4 ohm speaker, and a 12 volt power supply.
@@henriquelausch6999 I'm 56 years old.(born September 17, 1962) I graduated from tubes to transistors, in about 1970, and liked using the lower voltage, higher current, to build my small amplifiers. I really like being able to touch live circuitry without getting shocked, and, I REALLY like being able to drive speakers directly without impedance matching transformers limiting my frequency response.(especially on the low end of the spectrum)😁
this approach when used it needs an audio transformer ... not directly coupled to the speaker ... ... instead he should use a resistor from the power supply then from the resistor connect the speaker to the collector and ground respectively with a Capacitor coupled for the speaker ... he used this way it can be seen the speaker is taking almost 70% DC voltage which will upset the speaker and lead to speaker failure
At 12 volts, this is 9 watts, if that's a 4 ohm speaker. 6.3 watts RMS. This will put 1.5 amps on the speaker coil all the time, even if there is no signal. Without cone excursion to force air through the voice coil gap, the coil will heat up over time. for this to produce 100 watts, it would need to run on 40 volts, which would keep a steady 5 amps on the coil, which means that the voice coil would be dissipating close to 100 watts. That would force the cone beyond x max, and burn the voice coil to a crisp. you will need a lot of airflow over that heat sink as well. Remember, the transistors have to run at approximately 1/2 the supply voltage, the speaker at the other half. Because the DC resistance of a voice coil is slightly less than the nominal impedance of the driver, the transistors should be adjusted to maintain current, based on the impedance of the speaker, meaning the transistors will run at just over half of supply voltage, while the speaker coil is slightly less. This is a wildly inefficient set up, and is only suitable for very low power.
@@vincentrobinette1507 You are correct the first amplifier I built was similar to this and class a. To fix the problem of the dc offset that will kill the voice coil you need to add a audio output transformer to the output before the speaker.

Exacto amigo pero quieren engañar a la gente nunca podrá obtener 100wats con tan poco voltaje y menos a como lo hace yo aprovecharía esos transistores para un mejor proyecto
If you making the right minimalist push-pull circuit with an interstage transformer, you can take more 120 watts from two transistors. Circuit on video can't work for 100 watts, max one or two. So in this way don't make amplifiers.
se entiende que entre mas transistores conectados en serie mas watts de potencia, pero entre mas transistores la fuete tiene que tener mas amperaje minimo unos 5 amperes
It's not 100 watts. The DC bias might damage your speakers. Don't built it, unless you use a bigger heatsink and an output transformer. Also use a bipolar cap... It's a very bad amp after all, uncontrolled open loop gain etc.
Viendo el diagrama bien, el mismo tiene un error, el parlante si se fijan bien tiene aplicado constantemente un voltaje de 12 voltios, esto a medida que avance el el tiempo terminara quemando el parlante. yo aplicaria voltaje simetrico al circuito para que el voltaje que llega al parlante siempre sea de 0 voltios.
it"s imposible. You can"t get 100W from 12V and one more thing... Static current flows through the speaker. Speakers don"t like DC current. And it doesn"t have temperature stability. Very bad idea but it even works...
What can I do with 2 channels of them? and a cellular plug each going to one of the channels?, each channel having 5 transistors? How can you make one of these?

Why? No transistor balancing, no termalpaste, common connecting over heatsink? Don't teach starters bad habits
.... Add NO POWER SUPPLY!
Looks like linear, class A amplifier, without feedback to produce a lot of distortions.

it is necessary to do the decoupling of the constant voltage through the capacitor.
You risk destroying the speaker.
