Some nice progress on the Melbourne integrated preamplifer/HPA motherboard and power supply board by JPS64. I am in process of carefully checking routing and component pins, orientation etc.
As you can see, it's another masterpiece by Jean-Paul! Thanks for the superb design, JP.
It is a 6-part break-away board with 3 optional pot mini-boards (plus the one that is on-board the main PCB).

I have asked Hugh, and in thinking about it, OZ is the motherland of Melbourne. So it could be called the OZMEL Preamp. Let's see what Hugh says.
I have verified the schematics and Gerbers and found some small silkscreen typos - nothing that requires re-routing. Very nice work, JPS64 - as usual. Wonderful treatment of the various ground-planes and where star ground hub is.

I want thank everyone for being really good with getting me your info and paying the invoices quickly. I will place order for the boards today. I am upgrading the boards to 2mm thick, 2oz copper thickness, and gold ENIG finish and blue solder mask. These should be very nice boards and solid.
