Advice on vibration damping material for a power amp cover

[Hudz]

Hi all I'm looking for something to deaden the vibrations on an amplifier cover, the toroid hums a bit when there is no case on but I can live with that.

The problem is when I replace the cover the vibration/hum is amplified to a level where it is noticeable in any lulls in the music, and I can't leave it off for fear of cooking one of the many furry critters running about.
So I am looking for something thin (no more than about 5mm )and self-adhesive but hopefully not bitumin based as it's a class A power amp and does get a tad warm and I don't want something melting into the innards. I was thinking of using the car deadening stuff but all I can find has a bitumin layer.

Any advice/recommendations?

You could try a few strips of this stuck to the underside:

Something like this is usually very effective Martin http://www.ebay.co.uk/itm/RATTLEMATT...cAAOxy1klRdWl9

Yeah don't use that Dynamat, I had that on the inside of my amp cover that the previous owner had fitted and it took 3 hours and many chemicals to remove!

I'm sure someone will be along with an alternative.

I didn't think I'd be alone in having this problem thanks for the advice chaps.

@Shane never would have thought of a golf product, nice one, bout time that "sport" was good for something.

@Brian looks like the stuff in my CDP that I can't for the life of me remove but at least the bitumin is covered on your recommendation, the stuff in my CDP above the valves is just bare bitumin so I leave the cover off for obvious reasons.

@Mike sounds like the same stuff as in my CDP, evil, impossible to remove stuff that definately should not be fitted over tubes

Thanks Robert.
This looks like the winner, thanks for all the time and effort chaps, much appreciated

I was thinking of that stuff as I saw you had it in an item you were selling but I didn't know what it was, no doubt similar to what they use under car bonnets 👍

I suppose the other alternative is a thicker cover?

Yeah, Colin Wonfor had my amp in for a minor repair and removed the Dynamat with some nasty chemical and it took him 3 hours and much gnashing of teeth and sweat no doubt. I'm just glad it wasn't me who fitted it, but I know who did 😉 😀

Its fine in speakers etc but not in anything that gets warm.
