r!sc! · 16th July 2005, 02:36 PM

Hi,

is there anyone who have good project for metal enclosure for power amp (in any CAD software or picture)? Can u suggest me any design (not to complicate, just to be firmly)? Picture show the layout of the amp.

Thanks.

Ideally, the heat sinks should be mounted outside of the enclosure. If you get the right heat sinks, they can be used as side panels, and easily cut and acquired flat panels could be used for the other panels by bolting them to the heat sinks. Square rod can be used in the corners to help bolt the sides together to the heat sink.

Here are some helpful sources - perhaps.

None are plans or kits, but they are helpful.

You could also go into a second hand shop and pick up a cheap amplifier gut it and use its case.
I used an old switch mode power supply case for my power amplifier for 5 UK pounds.
The circuit and transformers are mounted on a steel chassis within a solid steel case on rails, so it can be removed and fiddled with at will!

This will often save lots of money and effort and can look as good as a manufactured amp if you find the right case.

Thanks. The heatsink is just 75mm high, so they cant be used as side panels.

Have a good wooden board, paint it white, keep wires hidden under the board, and fix it into your wall.

Do not cover that beauty...let people watch it.

Not Kidding.

regards,

Carlos

Are you sure those are adequate for a power amplifier???

Depending on what they are meant for. For inspiration, here is two specimens I just finished today. The smaller one would be nice for a small ClassA amp or a hefty classA/B amp. The bigger fellow, well go figure.... If you wonder how the finish is made on alu-plates, have a look at this:

Here's a link for some other heat sinks. You might find something like this in Europe, though:
