How to build a 21st century protection board

Here's how I'd like the final configuration to be. Main transformers will mount to the front cover. Supplies will tuck up to the transformers. Power relays will be under the power supplies. All high power wiring will be in the front of the amp and down through the center at the bottom. The input sections will be at the top rear, with onboard RCA connectors poking through the rear cover eliminating input signal wiring. The only part I don't like is the position of the control transformer.

Don't you love it when a plan comes together. All your careful work shows. I'm excited to get valery's Ns ops running myself. If history repeats it should sound great.

Who's the brave soul that's going to try a dead short rail to rail to test the disconnects?

There's no current sensing on the supply. These are just solid state shut off relays. A dead short would blow the rail fuses on the supply though.
 
So the relays would help limit collateral damage to the amps if something goes wrong.
I recently dropped a small piece of wire across the power supply of one of my amps..the fuse blew but the charge in the caps vaporized the wire... Stern reminder to be more careful.

Have you chosen your speaker connectors? I really like the speakon Connectors.
 
JW,
I think the skill of running a mill manually shows what you can do. CNC is nice for production but takes all the skill out of it. I've done some pretty complex tooling on a manual mill with nothing but a bunch of number coordinates, it can get crazy trying to keep track of where you are but I always put a location hole just in case I lose my place and have to go back to the original origin or with an older mill the slack in the screw when you change directions and have to pick up where you truly are when you can't go by the veneer scales on the handles. Of course glass scales take care of that but I've done it with nothing but the mill no readouts.

Nice work, it looked like sheet aluminum and a louver press could make something similar if you had a brake and louver press.
