Okay, I received the PCBs from the fab. It's pretty. Measuring a tiny 2-1/2" by 2-1/8".
I'm selling a few extra PCBs as I ordered a few more than what I needed.
Cost is $20 per board.I test-built one of the PCBs to test that it's working properly. Here's my completed prototype PSU (+44V) and (+48V) for phantom power, suited for those racking their Yamaha PM1000 channel strips.

And here's a shot of the bare PCB.

I have a few extra PSU boards so if you're interested, the cost of the PCB is
$20 each, +cost of shipping fees. I'll include a Bill of Materials with Digikey part numbers along with your PCB so you can order the parts direct from Digikey or Mouser or wherever.
Email me if you're interested to buy. Thanks!
