The eurocard, also known as a laboratory card, is an assembled circuit board with the dimensions 160 x 100 mm and, in addition to the Dannerkassette, the most common format used in vintage German broadcast technology. In this sub-category you will find cards with transformers only. These transformers were mostly made by the german companys Haufe or Pikatron, but there are also some cards with Lundahl or Beyerdynamic transformers around. These transformers can also be found in many of the Dannerkassetten. It is often said, that the sound described as "vintage" is "in the iron" of those transformers. :-)
