[R-390] C553 on newer EAC IF module

Gentlemen,
I am going through a 67 contract EAC IF module and was wondering what everyone thought about replacement of the “killer cap” C553. This module does not have any of the bumble bee bypass caps so common to the older contract radios and it appears that many of the caps that were used are all higher quality appearing “West Cap” glass sealed capacitors, including C553. Would you still change it out considering C553 is such a critical item? I realize that the “orange drops” are thought to be top of the line for this particular part of the radio, but I would not wish to change out what might in effect be a better part and replace it with one of lesser quality. Thanks in advance.-Brad
