As promised in my review of the Nord Three SE 1ET400A Dual Mono amplifier, here is a tear down of its construction. Since the individual modules are known quantity, I didn't try to take close up pictures of them. Instead, my focus is on the overall assembly of the unit:
From high level, assembly seems neat and tidy. I checked the grounding and was pleased to see that anodization coating was properly removed and nice ground lug attached to it.
I was also pleased to see custom length power supply to power amp wiring harness. The one closer to the amp has a shorter lead which is nice. This however does point out the asymmetry in design. The top amp has to have a longer power lead and over that drapes over the amp. Two independent boxes would be superior in this regard. We can see the same lack of symmetry in the way inputs are routed.
I am not a fan of double stick tape that is used to hold down a couple of wire bundles. The worst one is sitting on the top power supply heatsink. With constant cooling and heating it is bound to lose adhesion. Why not route it as I have shown with white arrow? Those are high voltage mains wires by the way so would be good to keep them separate from everything else. For that reason, I like to see them not go over the amplifier modules.
I am being very picky of course. I have seen some real horror stories in such builds. Here, we have nice and tidy construction. Lots of heatshink tubing is used to keep things together which I like.
So overall score is "good."
