Yeah, make sure the HV regulator circuit is regulating.

I immediately thought "this will be easy" and made sure that I had the 2
STK's for convergence and an audio out chip with me (in case).  I was
surprised to find a hv arc coming from the anode cap of the green crt
instead!  I removed the cap, cleaned the area, installed a new cap and
sealed it.  Great pix!  Thought this was certainly better than replacing the
STK's!
> Three days later the customer called and said the set was arcing again.
I went back with a new green crt assembly even though I was sure that I had
done a good "seal" job.
> Surprise.. The HV divider assembly had cracked open on the side and hv was
arcing everywhere.  I thought this was really too much of a coincidence so I
ran out to the truck for the hv probe.  Of course it had been a LONG time
since I used the probe in my truck and was not happy to see that it only
measured up to 30KV.  Well, it pegged the probe but I know that the hv in
this set would be 35kv with nothing connected to the crts.
> I ordered the divider and it arrived Friday night but I was wondering if
anyone has any thoughts on this before I return.
