Layout and faceplate is looking great. I hope inside isn't a crazy ball of twisted wires, but doubt it looking at the rest.

It is surprisingly hard to line up a quality faceplate with all your internal electronics, even using modern CAD. And by hard I guess what I really mean is extremely time consuming! But it only takes one small mistake to balls up a whole go. Great effort by whoever made that.

Looks like custom pcb's through the xlr cutouts.
Nice work!
What design are the eq's based on?

Nice build. I have been doing some organising of my rack/pre. All cables are pretty much tied in and connected, previously I have had to wire in everything each time I played… a bit of a pain. 

Now I can roll in, power up, leads out to speakers and play..! All effects to hand and close to control all levels.
