Default Just another Aleph

A friend of mine asked me to built an Aleph 5 monblocks for him. He is using the same heat sinks I used for my Aleph 5 (toaster amp), but this time 3 of them. This will be a pretty big amp.

For the 3 panels we used 3/8" aluminum extrusions in 12" width. There is no angles inside, everything is butt joined and the holes for the screws are drilled directly into the edges of extrusions.

nice casework!

you really like metal works!

are you using 6mm aluminium pannels? if so do you know if they can be cut with a hidraulic gillotine?

how are you going to finhish it? the yellow sinks and the aluminium "grey" panels doesn't look like your job!!

The panels are 10mm thick so they were cut with a saw. Truly it is not my personal work, cause the guy picked the parts and I'm putting everything together, so some of design ideas come from him. I only do what I can to make it look good. He will have it professionally finished by the same company that does Bryston an Sonic Frontiers. Heatsinks will stay probably gold and the rest will be clear anodised. Everything inside will be p2p connected, so by saving on boards we can us Cardas jacks and binding posts.

10mm?

why is that?

couldn't you find anything thinner?

I gess 3 or 4 mm for the pannel and ok 10mm for the front panel is good, but 10mm for all sound like a hell of a job. Even with your fine powertools and technics

Hell of a job or not. When you cut everythin with circular saw the thickness is not really important. I was cutting 1/2" succesfuly that way.

However by using thicker material we were able to eliminate the inside angles completely, so connections are very easy and the number of parts is reduced drastically. Everything is butt joined. It is still nothing compared to Krell subwoofer with walls of 26mm or more.

It's just a different way to do things, maybe something to think about on a next project. Thicker walls also resonate less.

I also bolt everything to the sinks.

I don't like those angle connectors that everybody uses.

I tap the sinks and bolt the panels to it. easy and if the panel has enough inertia ( 3 or 4mm is good for me in my projects) , it will not bend with self weight and even with the transformers and caps (i make deformation calculations to see if the pannel is thick enough)

my problem with thicker plates is the cutting. I dont have any circular saw like yours nor place to put one of those babies.

I use manual saw and power jigsaw only.

Maybe it's not just another Aleph anymore?
