Depending on how TR is combined, 3 types of amplification circuits are possible as above. (The same applies to FETs)
And compare the characteristics rather than the pros and cons.
For example, in the case of a CC amplifier, the voltage gain is less than 1. Therefore, it is not used for voltage gain, but mostly used for current amplification. It is also used alone for impedance conversion (input impedance is high, output is low), but
Most of them use CE voltage amplification + CC current amplification.
It is an audio amplifier, but if you look here, the voltage is amplified through the differential amplifier (T2, Tr3) at the first stage and then the CE amplifier (Tr4).
Current amplification is being performed in Tr6 to Tr9. Tr6 to Tr9 all correspond to CC amplification.
