Life of electrolytic caps shortens by 2 for each 10degC increase, starting likely from 50 years. Other than cap replacement from time to time, you should not worry - electronics should last. I have espresso machine constantly on for the last 10 years. It is very hot to touch and has electronics inside (microcontroller). It is still working and I expect at least another 10 years from it
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?
