2215 dim crt poor focus.


 

I'm working on a 2215 with a current limit board. The HV section is very clean so Im questioning if the CRT is actually bad. I know about the CRT over voltage issues with this scope. Here is a picture of one of the waveforms from the auto intensity and z-axis board. It does not look correct to me but I dont know if this is actually a problem. This scope came to me with the fuse on the current limiting board blown.
Thanks guys.

This is a copy of the waveform from the manual.
