I changed the sharing options to everyone. Just in case I also uploaded it to Scribd

Sorry!

(That's only V1.01. I've got a better one I'll upload later if there's any interest in this basic layout.)

Just my opinion...but I think your traces are way too long and way too thin for a power supply.

You need to make the large current paths as short as possible and use some filled planes

for the large currents. Check out Cobaltmutes R1 for a nice, compact design.

Yep, here's the updated one.

I wish eagle could tell you the estimated resistance of the wires on the board

edit: I'm also putting some effort into improving the design of the regulator, thanks to a later paper for this regulator

 

Ok, updated board. This really needs some work now to make it acceptable

Move the input voltage to the top of the board so it's much closer to the pass device.

The grounds can then be next to each other.

Are you going to use Wago Connectors for the wiring or just

wire straight to the board?

Flip Q2 around for better flow.

Then you can put the power input above the heat sinks

I'm trying to retain a star ground of sorts, I'd also like to keep the amount of wires crossing boards a minimum

I'll try to add support for phoenix closest to where the filter section of the PSU will be.

 

This is the final for the singlesided PCB, I'll start on the double sided later.

Also, does anyone have any extra 1.6volt LED's?

I finally decided to add some top planes, I don't know if this was a step in the right direction

Input?

I just need to add the optional OP compensation in case NE5534 is not used. I'd like to generate some interest for a GB, but I don't really know how to go about doing so.

You'll be able to find the schematic and improved schematic on Walt Jungs website. There are some other changes to the schematic, like splitting R20/R21 into two 7.5k resistors and running a electronic cap lead up to each power rail.

Thoughts?
