Hello all,
I was wondering what the difference between a power amplifier and a preamplifier was. Someone told me that a power-amp provides current and voltage gain whereas a pre-amplifier only provides voltage gain.
If this is the case, why are circuits like the following considered Class A Power Amps?
Does this circuit provide current gain? I think it only provides voltage gain, but I could be wrong.
