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?

Who is gratat thurmburg. ??.  ??

  Enjoy your amps.oh wow…..just looked her up. Ur gonna let some liberal 14 year old who is as dumd as a sack of hammers tell you what to listento..???

hahahahahhahahahahah

  play your class A amp all the time, heat ur room, home, apt…..
she is a whiny lil eejit who had her 5 min of tv time. 
  This reply is old as this spoiled insignificant, expendable idiot had her 5 min long time ago. 
I get my amps hott from constant hours of jamming, keep it up and enjoy the sweet music with your awesome lil class A heater !!!
Oh, and the climate is just fine...

Massive fires on the west coast. Increasingly stronger and stronger storms hitting the southern states. Northern Europe is being hit with sweltering temperatures.

And again, love how these "men" take every opportunity to dump on a young girl.

Must feel empowering. 

I guess that's just part of being profoundly ignorant.
I wonder if they couldn't add refrigerant to the heat sinks of a Class A amp to cool them. Don't laugh because I had a Marantz that used coolant in tubes that wound themselves around and through the heatsinks, no it did have a compressor.
