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?

When it comes, and it likely will come, it will come in the form of a consumption tax on electricity. A sin tax if you will. Or maybe a luxury item consumption tax (similar to a gas-guzzler tax). Just a matter of time.



I don't think that will happen because that would be a hit to electric cars, the powers that be wouldn't want that.
