Hi, I'm looking at the KPA100 schematic. I see Q3 (NPN MJE182) feeding U7B op-amp, and a reference to .6 to .9 vdc. It looks like Q3 is being used to sense temperature. I'm guessing its mounted on the heat-sink. U7B looks like a current regulation config based on the IR drop on Q3. Does this mean the amp automatically drops output power if the heat-sink starts to warm up?
