I wondered whom is right?
cathode oxide or
heater coating?
The heater looses emissivity.
Also the oxide from ION bombardment and local heating from the electron
beam gets burned.
In some systems the HV PS tends to fade over time as well!
I have a bunch of Acer tubes that did the latter when run at 800x600.
