I just measured my original Philco 4990 mica caps, they are both marked with yel.-gn. dots and they are approx. 35pf in value. Also part #17 does not connect directly to gd. but to pin #4 of the #24 tube exactly where part #22, the other 35pf cap connects. If you look on the Philco mica caps parts list, #4990 is listed as a 35pf cap. with yellow and green dots. I really can't tell if the small choke was factory or not.
Good luck with your project- I can confirm that both sch. available are filled with errors and I really had my doubts when I fired mine up- but it works good.
