Philco 48-200

The item you have marked as 1 is T400, the oscillator transformer.  See left side of parts layout in Troubleshooting for Section 4.  I would replace the 3-section electrolytic with three separate ones.  The voltages and color code for the electrolytics are probably marked on your item 2.  You need to unclamp it from the chassis and see if it will rotate far enough to see if anything is printed on the side you can't see.  If there are no markings, I would use 450 vdc replacements.  You would then also have to trace the wiring from each cap to see which wires connect to pin 7 of the 35Y4 tube and resistors R101 and R102 as shown in section 1 of the schematic.
