Life of CRT

[Audio]

I own a Tek 465. I am the "Nth" owner of this unit.
I purchased it from a rebuild/calibration lab.

It operates ok but the display becomes erratic when the CRT intensity is turned up to the extremely bright level (the 3 o'clock position), I think it is arcing internally causing the tube to "spit". For most of the work i do, the intensity level is set at a level where the spits do not occur (about 10 o'clock).

Is this an indication of a tube ready to die?

Thanks in advance.
