Simple preamplifier fast and with excellent results. I need it to detect night noises or whispering voices of my neighbors. :) I have been experimenting with piezo records for years but have not been able to get to a decent level. I ultimately want to create for myself a contact microphone that is super sensitive to noise variations. I am interested in getting to at least amplify up to 50 times an audio signal and beyond.
If you add a LC circuit ( 4 turn copper wire coil and a 100pf trimmer ) at the output of collector , you know you can make a FM transmitter too !!!! Make that a 2 in 1 circuit
@@RJEDITALL i just did your circuit and it works. however i have used 2n3904 transistor since i dont have bc547 and also replaced the 104 capacitor at the output with a 1000uF capacitor since it doesnt allows low frequency(bass) to pass throught. but once again thank you for the circuit.

Amazing awesome editing is your all videos.... congrats to you sir.
SJ ok ❤️
great👍 ... please make a 12v dc voltage subwoofer using the jrc 4558 ic please 🙏🙏
Ok
@@RJEDITALL thanks
Thinks you bhi rely work,😍
First like 👍👍👍👍👍👍

Thank you so much bro for visit
Nice Working lekin isme alag se seeti jesi voice kyo a rahi bo control ya kam nahi ho sakti kya
Bhai try Karke dekhle samaj ayega.
Nice👍
Thank you
Which amplifier you used??
Please make a video on how to make a preamplifire for clear sound......
Ok
@@RJEDITALL thanks sir
Can I have a video on how to make a powerful subwoofer?
Nice video 🌹🌹🌹🌹🌹🌹

Sir mic circuit 12v power supply me Banaye jaise Aapne 3.7v me Banaye h.. Thanks.
Ok
Can we supply 5V to this circuit?
What if we use normal dynamic🎤 mic to this circuit?please explain
yes
@@RJEDITALL thank you very much brother
Super 💕
Thanks
Can this be used as pre amplifier on audio music to amplifier?
Yes

Good content 👍🏻
If I use 5v,1amp from 7805 is there any circuit problem like heating problem or anything else ? And how can I use mic volume with it in any storeo
??
Bro if both mic and amp circuits connected with single power supply id gives full noise.
No noise problems
@@RJEDITALL bhai maine test kiya
😉😉🎤🎤👏👏
Thank you
Can I use ceramic 100 nF (104) capacitor or does it have to be film capacitor?
Yes
22 ke register replacement 1K register ya 10k please reply
Bhai, Sam components lagega
👌👌🌷🌷 🎤🎤💝💝
Puedes hacer uno similar para una guitarra eléctrica
Ok, thanks for visit
Apakah bisa menggunakan R 1/2 watt?
You can use 1/2 or 1/4 watt Rasistor
Plz make a amplifier with 2x 2n3055 transistor plz pzlz
Hello to boldaate😮
👍👍
Thanks
should not need an amp if you build circuit right
Bisakah menggunakan tegangan 6v atau 12v.?
Yes, you can use 6v
@@RJEDITALL thanks 👍
@@saktiakhmad37 but increase resistor value or Bc547 becomes too hot
@@jesusthesecond6847 thanks
अबे जो स्पीकर को तारें गई हैं, जिस डिब्बी से वो कब जोड़ा, वोट दिखाया ही नहीँ कब जोड़ दी।
Sir je mai isko 12v current du to
De sakte Hu. Transistor dekhlena heat hoti hai ya nahi
5 volt sai
👍🏻👍🏻👍🏻😃😃
Thanks
I have made this circuit but humming is coming out what to do please say me 🙏🙏
Please check well
What if I use 13001 transistor instead of BC 547
Yes, check transistor b c e before connection
