do it yourself simple powerful amplifier circuit with transistor D718 B688
Тәжірибелік нұсқаулар және стиль
Hello. do it yourself a simple electronic circuit to amplify sound powerfully. In this video I will show you how to make such a circuit. we need a transistor NPN D718, a transistor PNP B688, resistor 100kΩ, capacitor 100 µF, rheostat 5kΩ (you don't use rheostat, the amplifier circuit will work normally). The sound will be very loud and full of bass and treble. However, this circuit still has the limitation that the speaker must bear a large DC current of 0.7A, so you should use large speakers to avoid damaging your speakers. how? Watch the video and follow along.
+ Hope the video is useful to you. Good luck with your practice

Мне эта схема очень понравилась, и очень пригодилась в колонке на 300 wats

thank you
It will work. But the speaker is driven with a Dc-bias current. If the DC voltage is 12 Volt as suggested and the speaker is 4 ohm type then the DC current accross the speaker winding is 6 Volt / 4 ohms= 1.5 Amp's. That's not good for the speaker. And last but not least: This setup is far away from 500 W.

thank you. exactly as you said. I made a video kzread.info/dash/bejne/e2Rsr9iInq6qo7A.html. No more DC current to the speaker and it sounds better. Simple circuits have advantages and disadvantages
Mantap
falta especificar de cuantos watts rms es
es un amplificador de 240 rms watts mono
Jó hány w 10-15?

Thank you. yes about 15w
سلام من میشه با تقویت کننده صدا AB5417استفاده کنی یه امپلی قوی بسازی ممنون سید

The circuit makes my speakers pop. This will not be good for the speakers
Comentry के साथ दिखाओ वरना dis like
No se vio un huevo como están las soldaduras aserqe más la cámara
