[QUOTE="handsome, post: 114004, member: 772"] gloomy news for us who revel in them old old thangs....... surely the amount of 'atmosphere' that contaminates the vacuum cannot be that large if it enters via the bulb material? and do the getters die completely over time or can they be reactivated? i seem to remember reading somewhere that valves that had been in storage for a while should be operated with just the heater powered no HT, for approx 30mins to clear any gas. does anyone know about this?..........a worried handsome (i have a moderate sized stash of old 'uns) [/QUOTE]
