Well, you can get about 95% of the way there using the original Philco parts list.
You will want to replace:
1. All the ones listed as "Tubular Condensor". Some will only be available in modern values. .047 in place of .05, .022 in place of .02, .0033 in place of .003, etc. Buy all new ones with 630v rating. (see below)
2. "Line Condensor". These are the 2 .01 caps across the AC line. Nowadays people tend to use AC rated caps or "safety caps". In a pinch you can use regular 630v DC caps but if you're ordering you might as well get the AC rated ones.
3. "Electrolytic Condensor". I see two on the diagram. 16@200 and 12 @ 350. I personally would use 22@450 for both of them or maybe 22@450 and 10@450. Your choice of radial vs axial leads. Depends on how you plan to mount them.
If you plan on doing more radios in the future it wouldn't hurt to throw in a few extras as long as you're paying shipping. A couple rounds like that and you'll start to build up an inventory. Makes sense to stick with 630vdc caps and 450v electrolytics since they will fit most every old radio application. You'll probably find yourself going back to the well for some resistors too but after a few times you can get better at predicting which ones might be problematic.
Good luck,
Bill
