That's completely different from what these CRTs are doing. These have
spots all over and not an even discoloration that starts at the corners the

processes.
Not necessarily. I've seen ADM 3A terminals
that are perfect (I have a
couple) and I've seen some that are terrible (I have a couple).
At any rate, this problem has always been described by speculation and no
hard data. It's time we got some real answeres because if this damage can
be halted and prevented in the first place then I'd like to know how and
why it happens.
I agree 100%. I suspect that it's not an organism at all, but
merely breakdown of the stuff that bonds the faceplate to the
tube.
Automobile windshields pretty much all exhibit a similar
phenomenon; they get foggy (white) at the corners. It's known to
be deterioration/oxidation of the plastic layer.
Plastics degrade all the time.
But we need someone to test the "mold", which will be tough.
I would be EASY to test to see if it's an organic compound.
