Looking at the photo of the underside, it appears that you connected the .33 uF bypass cap in the wrong place. From what I can see, the cap is connected between ground and the plate of the 1st RF amp tube. If this is the case, you are bypassing all the received RF signals to ground, so it is not surprising that you have no reception.
The bypass cap should connect from the 67 V supply line to ground, not to the tube plate. Try removing the cap and see if you get any reception.
