This is a 4 transistor audio amplifier circuit. Which is a 4-transistors complementary push-pull amplifier, that shows the basics of audio amplifier design. This circuit saving on battery current, which is quite low with middle volume, rising to 25 -30mA as a volume is increased. This gives us a 250 mW amplifier

Which is a 4-transistors complementary push-pull amplifier, that shows the basics of audio amplifier design. This circuit saving on battery current, which is quite low with middle volume, rising to 25 -30mA as a volume is increased. This gives us a 250 mW amplifier, enough to drive a loudspeaker to the same volume as a mobile phone or MP3 player.

6 TRANSISTOR AUDIO AMPLIFIER MANUAL CHAPTER 1 Amplifiers with outputs of up to 10 mW. The first transistor amplifiers were, of course, in the very low power range and it is in this field that the transistor has scored its greatest victory because valves, at these powers, are hopelessly inefficient. Even the subminiature hearing aid

What speakers should I use for the new Sony TA-N86 amp, which has a switchable Class A and Class B section. It is not an hybrid one Class A/B. It has a separate switch in a power supply for each Class. It is not a tube amp, purely Transistors, without any ICs. A wattage for Class A is 2× 15W. Class B has circa 75W.
