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?

I'm guessing your temp measurements are in degrees F, not C?
