DIY Eurorack-Case, the Power Supply Boards arrived

The Eurorack Power Supply Board

Today the PCBs arrived and I had to start soldering one immediately. You will notice that the layout is similar to the Doepfer PSU. I tried to develop a complete own board but I have to admit that the design is compelling. The circuit uses the LM 317 and 337 adjustable regulators, they deliver the +12V and -12V, a ringcore transformer, a bridge rectifier and a few other parts. I tried several layouts with this parts, but the Doepfer layout is the best. I think they perfected it over the years. I know that my board is a copy though but it was still a lot of research needed to get all the parts together and finally create the layout. As I will need at least four PSUs, I decided to let the boards be produced by a company. But this only makes sense if you order more than 10 or 20 pieces. So I might have some “in stock”…
First I have to finish my prototype to see if everything works as expected. Then I will order the parts for the “serial” production.

DIY: Creating a Eurorack-Case from scratch

This post was about the beginning of my DIY case journey. The next steps can be found in a more recent post as the journey continues.

Currently I am working on my own Eurorack case for my modular synth. The idea is to have a console like housing with four rows. I create everything from scratch. At the moment I am working on the PSU. The case will need four of them. The PCB layout is finished and I am waiting for the boards to arrive. The boards are based on the Doepfer PSU. I was lucky to get the original transformer, and all the other components. So I am quite confident to create a PSU which is as good as the Doepfer PSU. I will try to share all my experiences.
