@ regiregi22

Clean & tidy layout.

Is that a Hifi2000 case (BTW I have problem loading their website just now) ?
Looks like the mounting angles and the bottom / top plates are made from galvanised steel and partly power coated.
Am I correct ?


Thx in advance,
Patrick

Thanks for your compliments, one of my first aims was to separate AC power wires from signal ones, and placing power transformers away too. The other was to separate small signal from power output to avoid oscilations.

yes, it is an HI-FI 2000 case. What I'm not sure if about the galvanized steel, I would say yes but I am not an expert in materials. Even don't know what is a powder coated steel or how does it look like.
Attached is another case I bough for my last project. I strongly reccommend this manufacturer if you are looking for a very solid and resistant enclosure.

Regards,
Regi

If you could find a piece of magnet, then you could see which parts are attracted to it.
Those would be made of steel.

Judging from the photos, I would bet that all are steel except for the thick aluminium front panel and the two heat sinks.

I think there may be options with top and back panel in Alu as well

Patrick and JBdV are both right.

On some product lines they use more Alu parts - you can tell by the price.

I've been tempted to build a F5 into a hifi2000 case, but the heatsinks were a bit of a concern - are they big enough?

It probably depends which Hifi2000 chassis you are planning to use. They have versions in 2U, 3U 4U and 5U (height). The dissipation capabilities are scaling accordingly
Here are some numbers (french but a Watt is a Watt ) :
5U - HIFI-2000 05/500B Boitier Dissipateur 5U / 500mm - Façade 10mm Silver

Yeah, I said I wasn't sure about the exact composition of the tray, but for sure it is NOT alu, it has to be steel. As Patrick said, you can check the materials here:
modushop.biz
I will try later the magnet checking

Spev, don't be afraid about modushop's for an F5. Just take the Pessante Dissipante 4U or 5U height. 3U is not enought, specially if you are placing a discrete diode bridge of 8 devices in each heatsink as me. Take the 5U one, you wont regret and you will be able to bias it higher than 1.3A. You can even choose a deeper case (400mm instead of 300mm).

I hope this helps,
Regi

I have tried with the magnet from a speaker I had lying around, and Patrick's assumptions were correct; The tray, the mounting angles, the top and bottom cover and the back panel are pulled from the magnet (well, the other way around in fact :-) while the front panel and heatsinks don't.
Didn't mind about it, but now I can see that this makes a quite strong chassis. When you hold it, feels like you cannot break it even if you throw it against the wall

Yes they do have versions with aluminium plates, but the angles and the screws are still most likely steel (magnetic).
