Lightbulb A simple chassis idea

A friend asked me to make a chassis for his passive preamp. I didn't want to spend too much time on that, so I had to figure out a smart way to build a box, yet make it look nicely.

My idea worked well and I am more than happy with a look. But what was even more plaeasing was the fact that I only had to use 4 screws for putting everything together (including feet).

And this is how it's done. I used 2 x 4 rectangular aluminum extrusion cut to 5.5" length. Front and rear panel is done out of clear anodized aluminum angles. The chassis body is brushed and alodined, that's where the gold color comes from. Took me 4 hours to completely make 2 boxes and put preamp in one of them.

I figured it out today and I have to say that it's pretty simple and smart way to do a smaller box (crossover, preamp, phono stage). I guess I'll be using that technique more often. I remeber some guys complaining about using countless screws for a chassis. This one needs only four.

er, ... thats "cute little thang" I have to say that this is a real contribution. Did you do all the cuts with your trusty metal cutting circular say? My local surplus aluminum supply place is very pricey, but has a great stock of rectangular tube.

For a gain card amp or some such, it might be adaquate heatsink

As usually I used 10" mitre saw with non-ferrous metal blade. It's the easiest way to cut aluminum.
