Default Aleph J finished -- Thank you Mr.Nelson

I built this one for a friend. Thank you for this great amp.
Pictures say 1000 words. although you already know how it looks, maybe some chasis solution pictures can give you ideas or help with other projects.
Chasis was built in my friends workshop, another DIY enthusiast

This was first setup and I had slight hum issues which I solved by completly rotating power supply. transformer was brought to front and capacitor board on the back. central ground is now on the back side as close as possible to connectors. Amp is now dead silent and waiting for proper preamp. (p1.7 is ready to have new chasis)

Looks really super! professional ! Did you spray paint the aluminum black?
Isn't it a bit too much heatsink for an Aleph J?

Heatsinks and top cover are black anodised.
Centwr window on top is clear acrylic and side holes are black coated net for better cooling
Rear panel, sub fron panel and bottom and sub bottom (can not find better word ) are powder coated (black plastic). Front panel is 10mm black acrylic.
I've biased it much higher and one of the possibilities of placing the amp was in some sort of shelf so i didn't want to risk it getting to hot.
