This evening I again took apart the can of the 2nd IF transformer. I didn't remember seeing any capacitors inside there, although at the time I was busy checking the winding continuity. Again. the windings were fine, the resistor R21 was fine; but, as I remembered, there were NO OTHER CAPACITORS in there besides the two variable caps on the top of the porcelain cap. There is a green and yellow wire attached to a lug on the top porcelain with the two variable caps, which I surmise should be the central grounding wire between caps 23 and 24, but there is NO SIGN of caps 23 or 24! I know the radio DID work when I first tested it, so it was working without these capacitors. What purpose do they serve? Why would they have been left out of my radio? Did Philco often make undocumented changes? This must be fairly early production because R11 was still a 70K resistor, and that was changed to a 40K later in production to improve oscillator production. (I have made the change) This is a very curious radio !
