Thanks Mike...do I get to choose which answer I like? 
Just kidding.
Here's a better drawing and the relevant photos for Mike N's D-10 phonograph in the 46-1203 radio and a D-10 schematic in a 1226.

In the actual phonograph, the shield on the crystal cable could be connected to the phono chassis ground at the point marked "X" in the first photograph rather than lug# 3 in my drawing. Electrically they are the same point since he black wire on the wiring lug #3 in my drawing also connects to the phono chassis ground via a screw in the chassis. The capacitor is between the radio chassis ground (grounded via the cable shield grounded somewhere inside the radio chassis) and the phonograph chassis ground. The red wire from the crystal cable connects to the yellow from the radio cable at lug #1 and the black wire from the crystal cable connects to the radio chassis ground + one end of the capacitor at lug #2. Wiring lug #4 is not used.
