Modular Synth (Eurorack) - Case
I used a walnut board, cut it to size and planed it to 25mm thickness. I
decided to build an 84hp width 12u case, with a depth of 200mm.
I cut and planed the boards. I decided to biscuit joint them as I wanted to
be absolutely exact on dimensions and wasn't confident cutting dove tails and
keeping dimensions to within about a quarter of a millimetre (to fit the racks
The back was made from plywood which was stained with a spirit-based walnut dye.
After closing the carcass, I used Liberon Finishing Oil (with no sanding sealer).
I applied eight coats and then waxed with Black Bison wax.
Power and Mounting the Modules
Doepfer A-100 DIY Kit
I bought a Doepfer DIY kit which consists of two (6U) 84HP rails, a power supply
and two bus boards. I mounted the power supply and bus boards on PCB standoffs on the
back of the case. I used XLR caonnectors (rated > 2A) to connect the power.
As the rack grew, I bought a second kit for the next 6U.
Second DIY Case
This will probably a quickly knocked up plywood 6u case built around synthrack rails
and Frequency Central Routemaster power supply/busboard.
Frequency Central Routemaster
I started building two Frequency Central bus board/power supplies to use as a test
power supply, with the long-term plan of mounting them in a 6u case later.
I decided to build a case using Synthracks 84HP rails.
Doepfer LC9 (PSU2)
A second-hand LC9 with linear power supply (PSU2) was too much of a bargain to ignore, right when I had
just filled the 12u DIY case !
Doepfer LC9 (PSU3)
I built a lot of new modules and was too impatient to build the large case I have planned
so I bought another Doepfer LC9 (PSU3 version this time).
