"What might be fair to say is that A/B amps don't cease being class A when more power is demanded: only the peaks, '+' or '-' of the signal operate in class B mode. There is nothing magical about the shifting."
Then the definitions (and distinctions between) of Class A and Class B and Class A/B have lost their meanings.
I think Pass said what he said, the way he said it, just to get a point across to the non technical reader.
I think he was really saying something like this,
The amp is not Class A at low power but it has something in common with a Class A amplifier, the output devices don't reach cutoff (***like in a Class A amplifier***) when at low power. The amp is not Class B but it has something in common with a Class B amplifier when at higher power levels, the output devices do reach cutoff (***like in a Class B amplifier***).
But just because those two thing are "like" Class A and Class B that doesn't make the amplifier a Class A or a Class B amplifier. It is neither, it is a Class A/B amplifier. Class A/B amplifier are there own thing. Nelson was just trying to get non technical people to understand how they do what they do. He was not trying to re-define the meaning of Class A and Class B or Class A/B. All three are already well defined.
