Well here is a pic of it after a quick purity setup and degaussing.
It gets better the longer it runs. I have been using it for about 2 hours and it seems ok at 189mA cathode current. Until it goes through a cold start and the auto gedauss is used. It kills the purity again. Unplug degauss coils and it will be fine over several startups. So I am thinking the thermistors,varistors are of the incorrect value ? Causing current flow to be to abrupt (on/off)magnatizing the crt ? The coil measures 9.6 ohms
