in the philco 90 ( with 1 type 47 tube ) the part 28 and 23 bakelite caps have three terminals besides the ground is there two or three caps in these and how is it wired ? any help would be appreciated
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!!
Actually, that my website, The Philco Repair Bench, not this website, although we are site partners. ;)

i did see it listed with the number 3903 it did not have the letter m the schematic had i guess it is not wired at all to the screw terminal i saw the number 23 0nly once on the schematic i guess though it contains two capacitors
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
