  The ECC81 was the first double triode with noval socket introduced by Valvo in 1951. Most tubes of this type were not made in the Netherlands. Only very few came from the plant in Heerlen. The most common type (with VF1 code) was made by Siemens & Halske in Munich, Germany. Very extraordinary: The blue print 6201 and the coin base tube.
