6/100*MetalBase6\100 ist eigentlich die richtige Bezeichnung dieser 6/100 mit Metallsockel. Besonderheit an dieser Röhre: Die Heizung wurde durch eine "minimal-invasive-Operation" ersetzt. Siehe Galsveränderung in der optischen Fortsetzung des Systems. Das war die klassische Methode für den Ersatz eines Heizfadens. 31.Dec.2008 Ernst Erb |
