Since two years we do work on a very nice reproduction of the D type voltage regulator for the real early VW engines.
Our aim is to make these regulators with the closest look and feel like the original.
We will also sell the caps separately. Caps will be 100% identical and so perfect interchangeable with original D regulator caps.
Pictures below shows our test results for the caps….
Now we will stow a perfect electronic voltage regulator inside.
For later models we do manufacture and supply 6 Volt voltage regulators under BBT # 1951 off course also with a perfect interchangeable cap.
