I was looking at the 46 service info before work this morning. The RF tube plates are listed at 100 VDC, and the 71A output tube plates are listed at 90 VDC. So as far as your capacitor are concerned, 600-630 VDC caps are more than adequate as they will never see anything higher than around 150 VDC, if that.
I've never restored one - I have a 46 chassis and speaker, just waiting for a cathedral cabinet. I really did not intend to restore my 46 chassis; instead, I plan to just leave it as is and make it a "shelf queen."
I'll see what I can find out about your wirewound resistors, if I don't forget.
(oh, since we are discussing the electronic restoration of a Philco, I moved this topic to Philco Electronic Restoration.)
