Title: Age and noise
Post by: renluop on March 06, 2018, 11:18:02 PM

Not mine and not from life around me! My question is whether, as it gets older, an electrical item e.g TV, motor, switch is likely to be in increasing source of RF noise. Some of my stuff is approaching ten years and more.

Hmmm. Don't know about that...

But as my age increases, I am less able to hear AF noise.  :oldman:

It's possible as all components age the could possibly go "out of spec". Take the PSU fan in my computer which is now 5 years old started rattling the other day so I took out the PSU and squirted a touch of oil on the fan and all is fixed.

Considering the rubbing contacts of a commutator or a switch, age is going to make it tend to arc more and so generate interference  A  C R suppressor across it should help but if it is about worn out anyway, hardly worth it.
