The Bavarian Contest Club (Germany) designed a preselector in the late 1990. There was no complete kit but a printed circuit board and decals for labeling the front and rear panel were available.
Local (German) sources were shown for all of the components.
This unit was built by several dozen OM and YL's.
The circuit board and decals are no longer available, but there is is an Assembly Manual available in German and I have translated it into an English version, showing current (December 2023) sources for many of the components . (Downloads below)
