My memory is not that brilliant  but I have a feeling that at Neve we used a brass bus bar for B- (=AGND) which was tapped at regular intervals along its length. I am not certain but I suspect copper is a bit to malleable to tap reliably.

So you will need a BIG soldering iron to make connections to it.

Edit: Forget that, I just found that pre-tapped copper bus bars are commonplace.

Cheers

Looks good .   What is the estimated current draw with all the slots occupied.   That is all modules.

It's been awhile since I had things hooked up and I've yet to test vu buffer strips + illumination draw, so a super rough estimate with everything pegged and energised (which of course would never happen with a mix, ever) including slots,  perhaps 1100 watts if channels kept at stock 16v +/-
For 500 slots I had to take an average from API @ 215ma per unit, and assume tube stuff and clean IC slots offset for a total of about 330watts.

Course bus bars could likely handle 10x that and not even get hot.

I'll definitely stick a kill o' watt unit between the PSU and mains when everything's done and get real answer for ya (I'm curious too).
