The Braun Ausbausystem 2 (8200) was the second extension model and was a direct copy of the Egger 8200 model excepting the changes as previously noted in the Grundsystem (8000) model. This extension model added 40 new experiments and required possession of the 8000 base model. The focus of this model was ‘Advanced Electronics‘ and included zener diode, neon gas lamp, and high voltage transformer blocks amongst others.
As with other models with an Egger pedigree, Braun revised the Ausbaustem 2 with the vacuum formed plastic trays. In this case, the size of the box packaging was dramatically reduced to about 1/2 the size of the original box packaging.
One minor change (and it was not consistently applied) was the use of a dark yellow button for the normally closed switch block.
