The Single NPN Transistor Audio Preamp | HACK A WEEK
http://hackaweek.com/hacks/the-single-npn-transistor-audio-preamp/
The Single NPN Transistor Audio Preamp. Here’s a great little project that goes well with the LM386 audio amp. It’s a good first time transistor project because it’s simple and demonstrates the common emitter class A amplifier circuit with only six components in the signal path. A “Class A Amplifier” operation is one where the ...

Transistor tutorial Audio Amplifiers, Part 5 ... Thanks I will try that but I really want a transistor based preamp. I just like the warm fuzzy sound. Chips sound shrill imho. My power amp is powered by 45 v dc dual supply ...

Another simple audio preamplifier is shown on figure 4. This specific design uses also the same transistors used in the previous design, but differs from the classic pattern of a transistor preamplifier, because the base of the second transistor (see TR2) is directly connected to the collector of the first transistor and the signal output is ...

On the other hand, if you're trying to work into a transistor amplifier, it might load down this preamplifier. In that case, you need a buffer amp (such as an emitter-follower stage) or a different preamp circuit. A general-purpose BJT isn't a low-noise device as a JFET is. You can certainly use a low-noise BJT in this circuit, but you'll have ...
Simple Preamplifier Circuit using BC547 Transistor
https://circuits-diy.com/simple-preamplifier-circuit-using-bc547-transistor/
So here this BC547 NPN transistor acts as an amplifier. In the amplification configuration, the transistor allows a larger current to flow when we apply smaller voltage at its base. So here we are using a voltage at its base through the audio input signal by AUX jack, and it allows a larger current to pass from 9v battery source through the ...

Recommended: 40W transistor audio amplifier circuit with PC B. Which this C2, also helps to make the voltage at the emitter pin or the potential voltage at point D more smooth (from Figure 1). We only limit the sum of the feedback. Because in the basic amplifier circuit, High magnification is more important than high clarity.
