Hi guys, is there anyone here having a tube with "cathode poisoning" that is so severe that cant be healed? It should be a bare metal depositing on the cathodes, so I am very confused why it cannot be healed? What kind of tube it is?
I am now making a small research on "aging" new tubes just after manufacture (it was also used in original, industrially made tubes). They have pretty dirty (not visible) cathodes, covered by oxides and other residues, and I dont have any problem to make work every cathode. When the tube is new, it has pretty non-uniform glow, I think worse than "cathode poisoning", but after aging process, it works like a charm. I use now 7 hours per cathode at 15mA, 50mm digits.
