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.

31-35dB typically in the case of SR.

But that would be an unusually high powered amp - not the
run-of-the-mill 50 watt job.

Fifty Watts into 8 ohms requries 20 volts RMS. Having a gain of 20 would be
one volt input. That seems pretty typical to me.

In pro-audio, a kilowatt or so into 8 ohms isn't unusual. That's another 13dB
on top of your 26 giving 39dB but we tend to use +4dBu input sensitivity, so
knock of another 2dB approx making 37dB voltage gain in this instance..
