collection JR Jacob Roschy	6E8MG*glass By the designation 6E8MG the suffix "MG" indicates a glas tube encased in a metal envelope. Despite of this specified designation this tube lacks of this metal envelope. It's simply a glass tube with sprayed shield coating, as usual on side-contact-base- tubes. 15.Jul.2007 Jacob Roschy
