Maarten, I note from a previous thread about early trinitron tubes that a special tool is needed to remove the EHT lead.

I'm sure this is true of my set because I can see the H-STAT feed comes from the tripler unit and there appears to be only one lead. I therefore deduced the lead has to be concentric.

I've had a flashover or two so want to remove the lead and clean/HV grease the area. I also have intermittent sudden changes of static convergence. When these happen, it can be re-adjusted with the H-STAT control. Obviously the problem could be in the tripler but this is a sealed unit.

Any help in how to remove the lead would be appreciated.
