Class A Amplifier

[pidja105]

Hello,
I don't understand class a amplifiers much...For example, if I have sine signal of 1Watt and 12V, and I want to amplify it to 12W using class a amplifier, what transistor I need? I mean collector currents, and other currents and voltages.

Class A amplifiers are not good for power amps. You want AB or D.
