6H8MG*glassBy the designation 6H8MG 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 |
