How long does Class A have?

My Duson A10 runs hot too.

At first I left it switched on 24/7 to spare it the heat cycles and hopefully prolonge its life span. It’s 30 years old now and still going strong but I do switch it off now for energy sake. Also I use headphones on a Bluesound node while leaving the amps off more often, but that’s just being lazy.

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
