It has a sliding bias. It operated as a pure class A amplfier up to a given power then its bias changes to a class A/B operation. It is a high current amplfier capable of stereo 1 ohm loads.

25 watts minimum pure class A @ up to 180 degrees heatsink temp. Below 115 degrees it does about 45 watts pure class A.This is a function of thermal derating of the output devices.
