Son of Zen amplifier

[rendoman]

The amplifier begins to take shape!
The front panel is 15mm thick, I want to make a high pressure style porthole, not because it's audiophile but because I like it. Heads of allen screws (lateral) will be aligned with panel, the screws of porthole will be external.
I'm still undecided about rear panel and sides. For the sides got some carbon fiber plates or good wood (teak, oak and walnut). I don't want to use a full size rear panel, I still prefer a short one with all connectors attached and the back open air. There is not need to cover, no high voltage inside, main voltage parts will be insulated. Binding posts are granade style, 25mm dia I made some months ago with lathe.
