[Amps] one question test for hams

The answer is 'false'. And the main reason for that answer is the word '..all..'  
There are lots of reasons/mechanisms that cause or are a factor in the failure of a part and many (all??) of those mechanisms are accelerated by an increase in temperature (one 'rule of thumb' I remember is the statement that the failure rate for solid state device doubles for every 10 degC increase in temperature). Other factors are vibration, latent defects, etc. Some of these are going to happen even if you never turn the radio on (i.e. shelf life of a capacitor).  Regardless it is pretty much true that the cooler you keep things, the longer it will probably keep working.  
So keep it cool!!

"All failures of ham radios are caused, ultimately, by excessive heat."

​Come on, have fun with this if you can.  73​
