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?

As long as they keep making them and we keep buying them their will be a market. Never forget that rules and regulations are for “theee and not for me”. Every member of congress and the global elites have a carbon foot print that is larger than small cities. They own three or four large homes, fly private jets, are transported in large motorcades, travel with staff and security everywhere. Just go through the sequence. In the 70’s and 80’s we were going into a new ice age. Then the 90’s and 2000’s it became global warming, now it is climate change so they don’t have to keep changing their tune as the weather changes. I run class A mono blocks and NEVER TURN THEM OFF and if they don’t like it they can kiss my class A. I use my electricity on what I want to. Pay the bill every month and nothing they can do about it. EVERY scam or regulation invented by politicians is to serve only one purpose money laundering tax payers money back into their pockets.

sad reality about frailty of the human condition

I love my luxman... They do ab amps as well... My 550ax2 is amazing for my tannoys... I was debating getting the sugden IA4 as well but got a great deal with luxman so went for that... Either would make me. Happy
