How odd. Sylvania or Raytheon manufacture? Is the sticky cathode one of the guides or a main cathode? Is it in the immediate vicinity of the index cathode? Most 'sticky pin' problems I've seen were persuaded to go away if I could just get the tube spinning. Leaving a dekatron running for a day or so seems to sort out most things. Jon.
