Hello! Check the tech-section of this website ( Philco Repair Bench- Philco part values ) and click on bakelite condenser data provided there. You will need the orig part # located on the side of your condenser to match up with the diagrams provided. The diagrams will provide the info you are seeking. Good luck with your Philco restoration!!

ckc, part #s 23 &28 are 3903M and 3903P respectively. Each has one .01mfd, 600V cap. 3903M has cap between terminals 4-8 and 3903P has cap between terminals 2-7. Neither cap is grounded, they are by-pass caps. PL
