I may be succumbing to another geriatric grand mal brain fart
since this has been over 50 years ago. But the few times I've replaced that small electrolytic in a ratio detector, the cap was always 'upside down' with the positive end to ground.

Um.. don't you mean point D? Going by direction of conduction >, the diode is gonna put an excess of electrons (negative voltage) on pt. D
Compare to diode direction if pt. D were positive.
Again, I may be all wet, so all bets are off.
