Dr. Böhm various

Before Dr. Böhm invented self-build kits for electronic organs, he developped some organ circuits, i.e. glow (neon) lamp circuits. These circuits were also meant to be reproduced by people, who want to build an organ themselves, but there were no uniform solutions. So the organs looked different depending from the constructor, like this one manual Dr. Böhm organ.

The lady wife of Dr. Böhm is playing here on a two manual Dr. Böhm organ, which lead perhaps to the model DnT.
