Heat in class A equipment


Heat is one of the biggest enemies of electronic equipment. Does anyone know if this Heat is only at the output transistors and their heatsinks o8is it also present in other components within the unit. 

 

I was planning to remove the top cover and with a IR thermometer going to check temps..

 

Has anyone done this?

 Unless the amp is designed badly, the heat in class A SS amps is usually confined to the output stage.  And almost all components will be fine except the electrolytic caps.   The challenge is to keep the caps as cool as possible.
