I have several similar enclosures, but none that large. My largest is a 4U high where that one appears to be a 5U and not standard rack width. See my post #4202 above. Yes, they are great and solid chassis.
I know I'm dating myself, but as a young enthusiasts at the time and grad student, I couldn't afford the commercial kit, so I tried building one myself. Well that ended in disaster! Never did build one, but I sure wanted to. 🙂 Then life and family got in the way and now I have the means and time to play a lot more with my hobby. It's great fun. 😀
(If you prefer to keep it that way, I'd suggest to make the board layout less transparent and/or not post images)
All the circuits are designed and executed by me, Raimond. They were not commercial kit. Maybe in the future I'll make them as a commercial kit. Until now I made them as a hobby. Best regards, Raimond.
Hasi is from the Spanish hacer.

The Portuguese influence makes it sound good, no competition for Brasileira, but which language is.
All of my friends with Papiamentu/o roots are reasonably fluent in Spanish and Portuguese, besides Dutch, English and their mother tongue.
Goes to show how effective a very simple language can be.
Here's my almost completed build.
It is a Class A 100 watts bridged amplifier.
It is a heavily modified Modushop chassis. All parts anodized in blue I have made. I wanted to hide as many cables as possible so wiring is all under the transformers.

Most of the cabling is already done, just have to update some of the pictures.

very nice implimentation
but
a 100W class A amp with those heatshinks will explode very soon!

Where did you buy the pus boards and amplifier boards ? Want to share some more info 🙂 Id like to build a 100watt class a amp now..
Judging by the iec socket on the back panel those heatsinks are 30cm tall, which makes it 80cm or more deep. At a rough guess he's packing 10kg of heatsink there. Depending on the location of output devices and heat spreaders he could be fine.
Pinocchio what's the c/w for those sinks.
Pinocchio what's the c/w for those sinks.
for 100W amp the voltage output is 28.28V so suplly voltage is theoriticaly 40V practically aprox.50V
For 8Ω classA operation the current is 2.5A minimum!
so at least 200W per ch heat disapation!
can you handle it?
judging by what modushop actally sells. the biggest chassis the got is 210mm high and 500mm deep. wich make your judging impossible 🙂 and you don't see the IEC socket, as the back plate is not there.
this is a bridged amp. so the numbers are a little diffrent, but the dissipation would be the same. but i would say a minimum of ~250W dissipation pr ch actually.
the chassis can handle 1ch. but not 2.
there was the back panel. but is still is Maximum 210mm high and 500mm deep.
heatsinks are rated at about 0.095 pr side (if it is the 500mm chassis). but this is at 80+C and i would not even trust it. and you don't want the sinks even close to that temp.
