I'm going partially on memory here, but also on some of my pictures and the schematic.  I believe it IS connected to R315 in a roundabout way.  R315 is connected to the 6V6, pins 4 and 6.  Pin 6 is unused on the tube so is just being used as a terminal for a wire into the IF can (Z302) as well as C317.  Pin 4 is actually B+ and is connected to many places.  If I remember right there is a wire running from what I've called TS7, terminal 5 (where the top end of C328 is connected) up to the filter cap, C102B.  From there I think there is a wire that works it's way down to 6V6-4.  You should be able to measure continuity from TS7-5 to 6V6-4.
