I have built around 3 of these Chinese radios. Two AM/FM using a ZN414 for the AM which only gave poor performance on the MW band. FM worked fine.
About 3 months ago I built a HX 108 and that works fine. The trouble is that all the instructions are in Chinese so I had to do some detective work to work out where the 4 tuning cans would go. The position for the cans is as follows looking at the component side of the board with tuning capacitor in top LHS the tuning cans form a square Top LHS Grey top RHS White Bottom LHS Green Bottom RHS yellow. Mine worked first time. The only problem is keeping the 1.5V cells in place!

I have just looked at the circuit diagram and
B1 is the ferrite aerial coil
B2 is the black/grey can
B3 is the white can
B4 is the yellow can
B5 is the green can.
B6 is the green audio driver transformer
B7 is the Red audio output transformer.
Hope this helps.
