The resistor works fine as long as the supply isn't too noisy.

Thanks!
But I need some more help to understand :
What would be exactly the effect of a "noisy" supply?

Thanks for link ... but in defence of my inattention I must say I was not really aware of this question. Usually you don't see what you don't know...

Nelson, The increased bias current is shown to be a major improvement by the graphs provided. Is there any correlation that relates to the actual heat of the output devices. Does this heat which is causing the molecular particles to move faster attribute any advantages? I know there is a practical limit here.

Very nice article, makes things much easier to understand. Tad
 
There is a subtle performance difference with devices running a
little hotter, but mostly we make sure that we do all our adjustments
at normal operating temperature, and that means that we often have
to re-adjust after warm-up and burn-in.
