Diy class A amplifier mono powerful with transistors 2N3055 & C2073, output speakers using capacitors

[@Madmaxkkb]

Can I use 1/4 watt resistors..? Plz reply

[@CBTman99]

Very simple and effective single ended power amp. Using it with a cellphone gives it not only enough signal to sound well, but it also provides tone control, as a pre-amp would do. Using an output capacitor protects the speaker coil without much reduction of bass tone, it seems. Construction wide, I would use a solder lug for the connection to the transistor's collector to improve efficiency and strength. In addition, I would keep the C2073 as far from the 10 W resistor as possible to avoid temperature drift. Great evening project!

[@ShareTechCreative]

Thanks very much

[@wcmm1970]

right, I agree with the explanation. the problem will be to unite those of the output transistors in the double potentiometer

[@tgtube]

I managed to find, thanks

[@eoliver32]

Nice!

[@topquark22]

This is extremely cool. Will build! Thank you! Q: What is the model of heat sink to fit a TO-3 case transistor? Thanks.

[@shoaibmirza2402]

Wahoo. Great technical thing u manage baising this circuit never gos over heat because ur base resistance connected with collectors of darlington

[@ShareTechCreative]

Yes, you are right

[@Hasitha668]

yes

[@joeyscott4299]

Very Nice Design ! I've been wanting to try a darlington amp , thank you for continued inspiration my friend !

[@ShareTechCreative]

Joey Scott Thank you very much

[@saeidamirkashani2978]

Hi Sir, Thanks for sharing videos. Kindly please can any body help me to understand why when the circuit is on and the high amper circulate through emiter and collector which is installed on metal heat sink and no short circuit happens and why some use thermal paste and some not?

[@libmananchannel]

How many watts and how many ohms does the speaker use?

[@cursinoprs]

Hi. Good morning. Does anyone knows how many Watts we have in this Amp, please? Tks in advance.

[@user-tz5gb7kw8z]

👍👍👍👌super👋

[@wcmm1970]

hello, good morning, it would be possible to place 2 transistors, the 2 connected to a double potentiometer using the same design

[@ShareTechCreative]

You make an analog circuit into a stereo amplifier. If so, you need to pay attention to the use of mica to insulate the transistor, or you use two separate aluminum radiators to not touch each other, to avoid damaging the transistors.

[@dipaksardar1909]

How woofer size and watts?

[@geoathan1]

Can I use to replace C2073 with BD237 or BD139? I ask specifically for BD237, because I have some in my drawer.

[@ShareTechCreative]

Yes, can two-transistor

[@angelgrisales4644]

Buenas amigo espero este bien... Le puedo instalar otro transistor 2n3055 en paralelo ?

[@ShareTechCreative]

Sí, pero debe aumentar la resistencia de 10 Ohm / 10W a 10 Ohm / 20W y agregar un disipador de calor de aluminio

[@Nirky]

.090 A x 12v = 1.08 W power consumed. Class A great sounding but very inefficient, so maybe 300-400 mW output? Need 96+ dB speakers and a very small room.

[@twmodule9157]

✔️

hello, could you make one with 2 2n3055 and your pair mj2955. the guys from Brazil. thanks. (pandemic) very bad here only making amplifiers. thank you

It may be due to the power supply unit, you try to use the adapter power

you mean a switch mode power supply im not sure if i even have one that can supply the current
