SummerTime and Amp Heat

By "a matter of degree" I meant (along with a lame pun) the degree to which you're using the amp...running into a 4 ohm load to get 115db peaks for 5 hours might cause more heat than a day of light background music. I have a later MOSFET Forte' A/B that get toasty-ish only when I play something kinda loud for a while, but unless you have the amp in a VERY hot room I'd think excessive heat (risking shut down) is a design flaw, and the amp designer should have included fans. I'm amazed that some "all Class A" amps don't melt in "normal" use...but maybe I'm easily amazed.

When I received my Krell 300cx Steve at Krell said:
Don't leave it on 24/7
Yes it will run hotter than a lizards ass on a hot rock.
No don't worry about it as long as you have the required open air space as noted in the manual.
Now when I know it is getting hot I just smile and know she's just getting outa' 2nd gear.
Enjoy, John

OneMug,
I think blazing saddles got the idea from 'Treasure of theSiera Madre'....a terrific Bogart Movie. Alfonso Bedoya delivered the line which has been paraphrased in a bunch of movies, including some animal comedy where 'badges' was morphed into 'badgers'. fun for all.

Magfan, Good to know where it originated. Love movie quotes.

Magfan, good catch!

My feeling re the original question:
