Hello Karen,... sounds like you did a superb-job restoring your vintage chassis! It "is-normal" for the spkr field-coils And power trans to get pretty-hot to "touch", once these old vintage sets play a hour or so on modern type AC current!
I always use a 1-amp fast-blo fuse on one side of the AC line feeding the AC trans for backup "safety", however, that is not original if your concern is keeping the set "all-orig"? It just adds a "safety factor", just in case something goes wrong in the future, and can "save" the AC trans windings from high-current draw that can permanantly damage them.
Since your vintage set has been operating already over 1 hr increments, and everything is OK, ... your most-probably in the "safe-zone" already!! If your concerned, just add the 1-amp fuse on one-side of your lead-in AC line under-chassis. A properly working vintage tube radio shouldnt pull much more than 1/2 to 3/4 of "1-ampere" total. Enjoy your vintage Philco!!
