Transistors are used in audio amplifiers in different ways. You have discrete class-a circuits that overdrive well like the infamous Neve console mic pre. On paper an op amp designs will have the best performance (actually putting separate transistors in front of a conventional op amp is probably going to get close to the theoretical limit of performance).

Instead of adding more IC (such as LM386 or similar devices), adding two small transistor and several passive components can be cheaper solution if we can employ the unused op-amp section. Using two small transistors (2N3904 and 2N3906), we can build small power amplifier which deliver several hundreds milliwats.

from transistor to transistor (even if they are the same type of transistor). • Input impedance The input impedance of the common emitter amp can be calculated from the following equivalent circuit: Vin R1 R2 Rtin 1 Rin = 1 R1 + 1 R2 + 1 Rtin Rtinª DVB DIB = DVE DIE /b = DIERE DIE /b = bRE For AC case R1 and R2 are usually > Rtin so the input impedance is given by

Best sounding transistors - High-End Audio Discussion Forum

The number of output transistor an amp uses can dictate how well it moves the speaker. For example, when you compare an amp with 4 output transistors (2 for positive waveform and 2 for negative waveform) with an amplifier that has 12 output transistors, the transistors on the 12 amp will work 1/3 as hard for the amp to push the same amount of …
