Germanium Receptor V2 (2014-2017)

Frontpanel Cardboard-Test / Construction of the enclosure / Wiring of the control elements
Frontpanel Cardboard-Test

This is just a test to see, how the placement of the controls on the front panel will be. This front panel is currently made of cardboard, but at the end, the front will be made, of course,of aluminum :).

On the other pictures, I have documented the progress from the mechanical construction of the housing and the electrical wiring of the control elements.
