Now I am confused again because my 10BP4a has the coating like Erics 12LP4 where you can see through to the back of the screen. Another person said that the A suffix stood for alumanized when I question the need for an ion trap and what kind if needed (single or double) If mine is like yours than it must not be alumanized. Would that not mean a trap is needed? I'm never going to feel safe using this tube.....
