Now I have a question on part #59A on the 37-650 schematic. The 20ufd filter cap.

None of the original cans were hooked up and all the filter caps were slaved into this chassis. I'm restuffing the cans one of which wasn't even an original can and I noticed under the sleeve of one of the other cans that I'm not sure is original or not, no Philco markings or part numbers on it, and it has 20ufd 475V and 10ufd 50V stamped into the can. This coincides with the parts list for part #59 but it only says 20ufd and 10ufd on the patrs list.
I looked up the tube data on the 5Y4 and 5Y3 rectifiers and I believe a 450 volt cap would work fine but I thought I'd better get some expert opinions first. So will a 450 volt cap work in this circuit or should it be a 475 volt or higher? All the caps (including the 10ufd) that were slaved into the chassis were 450 volt but this tells me nothing.
Thanks,
John
