Can I use any transistor for audio amplifier?

Can I use any transistor for audio amplifier?

You can use any NPN transistor for Q1, Q3 and any PNP transistor for Q2. Any way the minimum collector current capacity of the transistors must not be less than 100mA. The circuit will work well with an 8 ohm speaker too, but the volume will be a little less.

How can we make a simple audio amplifier using transistor?

What is the transistor used for audio amplifier?

Since the 1970s, most modern audio amplifiers are based on solid-state transistors, especially the bipolar junction transistor (BJT) and the metal–oxide–semiconductor field-effect transistor (MOSFET). Transistor-based amplifiers are lighter in weight, more reliable and require less maintenance than tube amplifiers.

What is a 2 stage amplifier?

This 2 stage amplifier circuit comprises of two stages each of which perform amplification on the incoming audio signals and output finally obtained at the end of 2nd stage. A simple Microphone was used to feed input audio signals followed by a coupling capacitor C1 which removes any DC element from audio signal.

How transistor works as a amplifier?

A transistor acts as an amplifier by raising the strength of a weak signal. The DC bias voltage applied to the emitter base junction, makes it remain in forward biased condition. Thus a small input voltage results in a large output voltage, which shows that the transistor works as an amplifier.
