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?

I don't expect everyone to agree with my opinions.  I think that when there are people that not only expect people to agree with their opinions,but demand it,we have a HUGE problem.  
@arcticdeth She’s 18. She is addressing what a majority of the world's scientists have agreed on. Even the polluting corporations acknowledge there is an issue that will cost us money and quality of life. Of course the media lies. The rightwing spin machine has been fooling Americans for decades into believing what their wealthy puppet masters want the lower ranks to think by waving flags and allowing them to have guns instead of healthcare and college.
@arcticdeath.
Congratulations, you have confirmed both your ignorance and frail ego.

I wonder, have you ever left your own zip code?

it’s a big world out there sparky, and being an effective contrarian requires intelligence, experience and an education - one that extends beyond what TV and Google can provide.

Purple was never my thing. My 14 year old daughter however, loves that color. And both she, and my 8 year old son, are far better contrarians than you are capable of being. Intelligence, experience and education…
Can we stop it with these extreme political statements on this site. Come on guys. This is not the place to keep acting out your hostile political fears and insecurities. This site is for audio. I try to come here to escape this sort of behavior. You are ruining this site with this predictable and angry behavior. This is not the place! Time to just leave this stuff inside of your own head. Stop polluting this site. Will you please?!

Moderators, it’s well past time to start removing any and all political references. Period. The consequence of not doing so is continuing to see the site’s most experienced and helpful posters walk away from here slowly, but definitely. You know, the kind of posters who are kind, helpful and courteous. 

The blame also rests on AudioGon as it is your responsibility to keep this site an enjoyable place to come. AudioGon, you must realize past and current, best in class posters, are visiting here less and moving onto better managed forums. They just plain are. They post less and use your listing venue less.

I am dismayed that I even have to post this. It used to be common sense and part of being a well socialized adult to behave kindly and courteously.

It's the world we live in. The OP was incendiary from the get-go. There is a "Report this" flag function.
