CRT Operating Hours until Ion Burn Appears

Hi,

does somebody knows how long a non-aluminised CRT without ion trap can be used until an ion burn is visible on the screen? I have an English PYE LV30 with a MW22-17, this CRT has a slight ion burn:

I tested the CRT, and it has more than 1.2 mA cathode current, so I assume that this CRT was not used very much.

Kind regards,
Eckhard
