A good place for caps is Just Radios,

...good folks, and very helpful. They sell the yellow caps in 630 volts and those can be used to replace all of the ones rated for lower voltage in your set. They sell the electrolytics as well.
I was just noting that cap #41 does not have its negative connected to circuit ground but the other two electrolytics do. Cap #41 has its negative connected to the center tap of the high voltage secondary of the power transformer, as shown in the schematic on NostalgiaAir. It has to be connected for the radio to work, if not connected there would be major hum.
If this has an RCA jack, I'm betting it's not original. RCA was the enemy and Philco wouldn't use their metal tubes, much less their phono jack. I'm not sure, but think the RCA jack was invented a year or two after this radio was made, anyway. And I don't think you mentioned any way to switch from radio to phono on your radio, which wouldn't be a good way to sell a new set. My guess is that somebody added this input.
