• The LED's are awfully close to the mounting holes. If the screwdriver slips, you might damage the LED's.
• the top side needs a ground pour.
• The R6/R7 voltage divider components need to be closer together. Shift R4 left, towards C9 and you can move R6/R7 closer.
• If you rotate C9 180 degrees, the +28V line can be shortened up. tradeoff is the ground there gets a little worse, but adding a ground plane would mitigate this
• The 28V1 test point is very close to the connector, it's going to be hard to probe.
• LED on +28V line would be useful. 3 mA@28V isn't much power, and would be good to have.

• Added top ground pour
• 28V testpoint moved away from the connector

I think reworking the entire path of the 28V line is worth doing and I'll take a shot at it for the r0.2. I think I improved it a little in this rev.

I'm going to remove the mounting holes in the second revision, so not worrying about that for now. Thanks for pointing it out though. I didn't want to add a 28V LED since the Vout Enable LED should be acting to signal that the output is on, hopefully it serves the purpose. Once the mounting holes are removed, there should be lots of space to move the LEDs to be next to the BNC connector.
