When is hot too hot?
I have been enormously enjoying my “new” BeoCenter 9000 and while tidying up a bit noticed that the heat sink fins were warmer than I expected at approximately 110° F or 43° C.
I had been playing the 9000 for about an hour at “9” out of “15” volume.
A quick comparison check of my Beomaster 2400 after a reasonably hard work session produced nothing more than a “warm” 90° F or 32° C.
Both amplifiers sound great: no distortion, no malfunctions, nothing out of the ordinary.
So is 110° F or 43° C acceptable after an hour of play?

43° C is a nice summer day down here, so I dont think its too hot if it stays there.
Collecting Vintage B&O is not a hobby, its a lifestyle.
Was gonna say the same thing - that's an Arizona summer in the shade.

It will not win any green awards, but might make the music warmer. :-)

Thanks guys, I get the picture. I really didn’t “think” it was a problem, but thought it best to ask. I really have way too much time invested in this BeoCenter to have it succumb to an over heating problem I ignored.
Your responses remind me of the OLD joke, “It is 102° in the shade today here in Sarasota, Florida…… so for God’s sake, stay out of the shade!”
My well-adjusted Beomaster 4400 manages to get up to just over 50 degrees Celsius under hard working conditions

Hi Søren,
Thank you for sharing that helpful information.
In a different place and situation my Beomaster 2400 got plenty hot powering three pair of very inefficient speakers and I can well imagine it reached 50° C.
However today powering S45 speakers and working really hard it gets warm at most.
The same is true of my own handicapped Beomaster 4400; that said my 4400 reacts unfavorably to being pressed to play at a high volume so that might account for the difference in temperature.
In any case I regard this as very good news.
Thanks for your impute.
My BS5500 was running very hot for a long time. I'd set it up so that the left/right speakers were actually the front and back. That meant I could adjust the front/rear balance from the remote but also meant that the amplifier wasn't balanced - they were different sizes of speakers. Anyway, it must have been running like that for a long time but when I had friends round, one almost burnt himself placing a CD case down on top and brushing the heat sink with his hand. All is well now that I've balanced the speaker sizes.
