Welcome to the Phorum!
Hearing hum is good in that your speaker is probably working ok. Yes, your first item for restoration would be to replace the electrolytic and paper capacitors. There are several threads on restoration of Philco 60s that have appeared in the last few years (here's a link to mine) and a must read is Ron's Evolution of the 60 that will tell you which version of the chassis you have. There were many modifications and for the 60, Ron has done a remarkable job of documenting them. The electrolytics can be stuffed into the two cans that are on the top of the chassis after you empty them. If you use polarized electrolytics the negative side goes to the center tap of the transformer which is separated from chassis ground by the resistors in #47. There are threads and "how to" on this as well.
Post your progress and questions.
update...morzh posted while I was typing...and he's right...you will want to check your power transformer before you do anything. If all your tube filaments were lighted then you know the primary and the filament secondary section is ok but the high voltage secondary needs checking.
