Here is a schematic drawing of your tone control. Notice the annotations added in red by me.

Now, in pictorial form, using your picture. Annotations in yellow added by me.

One end of the first .01 uF capacitor connects where you see .01 uF (1) in the photo. The other end of this capacitor runs, via a wire coming from the tone control body, to resistor (54).
One end of the 3000 pF (.003 uF, or if you prefer, 3 nF) connects as shown in the photo.
One end of the other .01 uF capacitor - .01 uF (2) - connects as shown.
The other ends of the 3000 pF cap and the .01 uF (2) cap connect together and run, via your red wire, to block (63) and to the control grid of the 42 driver tube.
