How long does Class A have?


Hi Guys/Gals
 I have a Sugden A21SE which is a Pure Class A single ended design, I absolutely love this musical amplifier with its strangely plentiful 30wpc, it runs hots as they do, I always enjoy watching the faces of my uninitiated friends when they touch it after I mention they get hot, lol.
But in this modern green era I wonder just how long do Class A amplifiers have before Greta Thunberg gets wind of this inefficient method of creating sound and pisses on the parade?

Thoughts?

my amps run on 230v I guess they draw 1/2 the current and 1/2 the power?
No, your amp draws the same amount of current at either voltage, all other things being equal.


Wrong,  your amp draws half the current and twice the voltage as 115 volts and produces the same wattage.

Yeh, Greta and her type want you and your type to be around in 100 years. Can't imagine what her motives are.
Sorry old farts, Greta will have nothing to do with the obsolescence of your class A amps. Guys like Roberto Guerra, Bruno Putzeys and Merrill Wettasinghe are the ones you should be watching. They are designing amps that sound as good, operate much cooler and cost sometimes cheaper. It’s only a matter of time before class A joins the group of nostalgic products that are relegated to museums as I am sure your sons and daughters will not want anything to do with your class A amps in their modern homes.  So to answer your question, give or take 10 years.  Yes, vinyl will outlast them.
