What you describe could be "whiskers" growing in the ion pump. They do not affect the pumping until they grow big enough to load the supply past its current capability. You can sometimes remove them using a hand held brush discharge tester. (Remove tube from chassis before doing this!) I would not try this until the current rises enough to cut off the ovens. Your current is still quite low.
