Class A, AB

I saw some amps that are Class A, Class AB. Do these amps switch to AB at a certain power level? Where do they usually change to AB?

A 100 watt amp may put out 5 watts in Class A, then switch to Class B above that level. Even the most powerful A/B amps can only output about 15% of rated power in Class A. Typically, it's more like 5%.
