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?

Heat as the only enemy to electronics is not as simple as people say. Yes heat is one of the contributing factors to the demise of electronics but the actual failure comes from the heating and cooling cycle. Any good engineer will only use products with a heat rating that will work for the application. We all know the basic facts the heat will cause expansion and cooling will cause contraction. It is this cycle that will cause small cracks snd fractures in components. This is where the argument comes in to turn on and leave on as this eliminates the heating cooking cycle and will allow a component to run for a long time.
