Yes, you are right. Looking at the wrong outline diagram in my datasheet.
But the voltages are still somewhat different. Perhaps the 5ADP- that you say was once working was actually a somewhat worn-out tube that was subbed in sometime previously, and the weakened characteristics allowed it to focus properly with 5CP- voltages applied. Then you replaced it with GOOD 5ADP-types which will not.
