Lomo UP27 / ЛОМО УП-27 racking project. Recently bought four UP27 microphone preamps + PSU unit. Documentation so far:
The 6HE 19″ case has been bought here. Their website doesn’t list a 6HE model at the moment but if you ask they’ll be able to deliver. The base plate also comes from this shop. Side panels are regular 6HE eurorack rack-ears put in a 90 degree angle screwed on the base-plate (see 3rd pic). On that aurorack rails were screwed (see first pic).
Aluminium bars hold connectors in place. This way the preamps can be removed by pulling.
