Hi

What is the normal gain of a power-amp?


No single figure, but something around 20 times (26dB) voltage gain
would be normal. It depends on the output power of the amplifier.

And what's the normal gain of a pre-amp?



For most inputs (things like CD, tuner etc) no gain is required as they
already present the right level for the power amplifier. If the input is
a microphone, perhaps 40 to 60dB might be needed. For a phono input
there is no answer because of the huge variation of gain with frequency.
