Life of CRT

I own a Tek 465. I am the "Nth" owner of this unit. I purchased it from a rebuild/calibration lab. =20

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.
