    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

    For power transistors, the 'Base Current Range' switch (SW5) needs to be set to the high range (100 Ohms), and base current is limited to about 60mA. With a device having a gain of 20, collector current will be about 1.2A, but that will increase to 3A if the gain is 50 (more common with modern devices).

    The power dissipation by each transistor is PT = 10W. Therefore, power dissipated by two transistors is P 2T = 2 × 10 = 20W. Q15. A class B amplifier has an efficiency of 60% and each transistor has a rating of 2.5W. Find the a.c. output power and d.c. input power. Solution : The power dissipated by each transistor is PT = 2.5W.

Best transistor to use for audio amplifier - Electrical ...

    You could successfully build a audio amp from many different types of BJTs. It will be the circuit, not the transistor, that makes the amp work well. I'd pick jellybean parts like the 2N4401 (NPN) and 2N4403 (PNP) and stick with them for everything except for the final power output transistors. Lots of parts could fill that role.

    Regarding the sound aspects, perhaps they exist as with other components, but the design parameters such as the power supply, driver circuits, amount of feedback, etc probably have a much bigger impact. You very rarely hear of power transistor "rolling" as with tubes. rodman99999. Details. Discussions.
