    Getter flash spots changing over time

    Does it indicate a problem or age, etc. if a tube (6550) starts to get a gray coloring around the side getter flash spots. It was totally silver when I first installed the tubes and now the edges are turning grayish.

    Generally means the vacuum inside the tube is going soft.
