Dude, I really like those toroid mounts. Did you machine them?

Yes I spun them from some Delrin that I had kicking around in the Machine shop.

I machined them down from larger stock on a lathe and put a taper on the back end to really lock into the toroid. Drilled a bolt hole and machined out clearance for the bolt head so it locks in place. I blind mounted them with three screws from the backside on to flat Delrin stock and mounted that to the front panel. I was careful to sink the threads only deep enough to support the assembly without protruding out the front.

I also machined the Heatsinks from 4 scrap pieces to make them look like 2 nice new peices an a Bridgeport Mill, I set the shoulder hieght at .90 for the top cover, .125 for the back and .375 for the bottom. The shoulder width is .500 so I had lots of room to drill and tap to give all the surfaces the flush mount finish. It took a whole day just to finish the chassis.

I think the proffessional look really comes from Brian's boards though. The P/S solution is the best I have seen so far.

Looks good! How much bias current do you have per channel, and how warm do those massive heatsinks get?

I think that it would look even better if you used the current black PCBs I have had the boards made in blue, red and black, and black has been my favorite.

Click the image to open in full size.

I made my 8 channels with blue boards also though.
