Power transformer replacement??

[Tubejunke]

Good info.. Thanks folks!! No progress today. I feel like I can try the set with the black caps still in place. Sure there will probably be less than perfect performance but I can kind of check my progress so far with the whole power supply being replaced. Actually I went for a long time leaving those things alone in other sets because of that stupid color code. I have a book now that helps decipher what value thet are. Before that I just changed electrolytics, tubes, and bad resistors.
