This is Electronic Stethoscope circuits. Usually the stethoscope is a medical device that listens to the heartbeat. Which we can make it with the least amount of electronic equipment so easy to make.
Category: Amplifiers
There are: Car amplifiers • Mosfet amplifiers • Tone control • Amplifier ICs
• 12V amplifiers • Bridge amplifiers and more :
This is small integrated amplifier at 20W using a TDA2004 or TDA2005 IC,use 12V supply for BCL car audio amps
This is First stereo tone control board for a electronic students, so small,easy to build all in one PCB ,cheap. use transistors, few parts so low noise
The TA8225 is BTL audio power amplifier for consumer application. It is designed for 45W high power. Operating supply voltage: VCC = 9~18V
The Hi Fi preamplifier circuit project to tune smooth bass-treble, with a very low distortion. Use low noise transistors Frequency response range 20Hz-20KHz
