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?

Ugh here we go....Sugden has been making Class A amps since 1967! Some of those amps are still going strong today with little to NO service! Go take a gander at the heat sinks on say, an A21 integrated.....massive!

Beautiful, holographic, rich, full bodied sound.
