Will being off a little on the winding numbers have that drastic of an impact?
You can get the exact number of turns, when you turn the radio on, with the antenna coil wires connected to the radio (leave an ample amount of wire on the AVC line connection), tune in a station near the bottom end of the dial (around 570KHz) and add or remove turns of wire to get a max amount of signal strength. You can also bunch up or spread the turns of wire along the length of the ferrite core to make fine adjustments.
