Looks to me like you have one connection to the grid cap of the 6A8G tube, and one connection to pin 5 of the 6A8G tube. I only see the two connections on the schematic.

If there was a third one maybe it was a ground? Most of the time the ground are copper braid that usually soldered to the chassis.
