Hi,
I noticed that the top of my BM3500 gets quit warm when left on standby. Is it normal?
It gets warm to the left of the middle, in the cooling flange area on top of the plastic ribs, currently not wall mounted but lying flat. Yeah, the place where you would expect it to be hot when played, and it is, but how warm is normal at standby?

Hi Goran
It is not normal that it gets hot at standby. I've just checked my BM 4500...I can only feel very little heat...like a little over room temperature.If it feels hot, then something is wrong...
BM 2400, just hand warm or a little less, BM 5000 cool,
Collecting Vintage B&O is not a hobby, its a lifestyle.
I vaguely recall seeing a post quite some time ago saying that hot at standby means capacitors need replacement(?)
thanks for your answers,
hard to meausure our perseption of warm... if I hold my hand to the right side of the BM it will feel cool, this is beacuse it is 23 degreec C as the room, while my hand is somewhere around 37, and the part where it is warm is somewhere over 37.
after some hours of listening it is not much over this temperature, it was at moderate volume however. Nothing else indicates that something is wrong
since I became a member on the forum I have read on several occations about recap of beomasters.
is this a word to say; changing all capacitors on all boards, or is it changing all components in some areas? I can't say that I am experianced in soldering, but I have done some electric projects, and if I wouldn't have chosen to become an MSc. engineer I would have liked to be an electrician (still concidering) also since I in the first place bought the 3500 as a back up or donor for my 4500 I would concider giveing it a try.
Could be that the amplifier section is not properly shut down in standby.

I don't think the 3500 has the notorious red capacitors, though obviously other types will go out of spec with time.

I have a like fault in BM4500 years a go. There was one resistor burnt, dont know why. Sadly I dont remember witch one it was. Since then it has worked without problems.
blah-blah and photographs as needed
