I actually found one more mistake: remember this thread? There was that capacitor, with no position number next to resistor #47, which could not be found, and the questioned connection of it to GND?
The schematic here on Philco Phorum is still showing that, don't know if Chuck corrected his version yet.
Here's how it is: this cap is indeed non-existent, and the guess was correct, the lower contact of the left coil of the transformer #13 should go to the "D" voltage, where it is decoupled by the cap #29 to the "C" (rect. negative). There should be a dot there where the no-name cap upper lead crosses "D" line and the cap itself should be removed.
Here's the answer: the
