Congratulations! You have completed the assembly of the DIY case! Connect an AC/DC
adapter to the DC socket and flip the ON switch. Both LEDs should light up. If they do,
measure voltage between the GND pins on the eurorack power connector and the
-12V pins. Make sure you read about -12V. Then continue with +12V. If the readings are
ok, you can start populating your newly built eurorack case with modules!
