My Forte 4a amp has singing fins. I use stiff slivers of rubber at varying spots throughout the fins to dampen the ringing. the total area of the slivers is only a thousandth of the area of the fins. Bulky things to dampen the fins on a hot baby like my Forte would be bad. The 20 or so rubber slivers I use are 1/4 inch square and about 3/4 inch long are fine, I carved them from big chemical industry bottle stoppers.
Amp heat sinks are ringing
I have been working to reduce the slap echo in my room by using quick hand claps, and various foam panels to attenuate the noise. I have discovered that my Classe CAM 200 monoblock heat sinks are actually ringing- they can be excited by handclaps, and heard across the room. There are 10 heat sinks per amp, about 2" deep by 8" high. Running my fingers along the heatsinks makes them ring like a bell!
I am concerned that this ringing might be excited when I am listening to the system, and may add extra treble noise.
Does anyone have any suggestions for damping out the noise? I am concerned about using a material that can withstand the heat, and not impede the airflow?
thanks for your help!
