Instruction:
Align the IC in the correct position and solder opposing pins. Then solder each successive pin taking care not to short out adjacent pins.
Mount the hardware – the headphone jack, the variable capacitor, the volume switch and the band switch.
Mount the two copper air-coiled inductors and LED
Bettery case：Keep the terminals loose on your bench and solder a red wire to the positive and black wire to the negative
solder a pair of yellow wires to the positive and negative of the speaker.
Now, the screws need to be sorted and the dials installed.
three long tapping screws (pointed end)
two short tapping screws (pointed end)
two identical machine screws (flat end)
one slightly different machine screw
make the final connections and assemble the unit.
First, slide the battery terminals into place – positive is the top terminal on the front case, negative is the lower terminal. Tack-solder the negative wire to GB-, and positive wire to GB+.
Next, solder the speaker wires with both yellow wires going to one SP terminal respectively. The AM rod antenna connections can be made by looping out the enamelled wire (over the top of the PCB is best) and tack soldering the ends to AM terminals.
The final connection is the FM antenna connection.

Note:
Different people may have different approach to assemble it, you can also search on google or YouTube for more sharing and detail, hope you have fun with this Kit.Not recommended for beginners!
