Using a soldering iron you will need to extend the connections between the circuit board and the speaker, battery connections, volume control/on off switch, tuner and aerial.



Using a soldering iron heat up the current component connections to the board until solder is fully melted and using a solder sucker remove all traces of the solder.



Once done the component will then come away from the board. At this point it is useful to take images or mark the component in some way so as to connect to wires back to the correct holes.



Cut a strip of wire to your desired length and strip both ends to show the metal core. I used multi core cable in my design as due to the hinged movement of the radio single coil has a greater chance of breaking. Touch the wire to the component connection and add a small amount of heated solder to create a solid connection. Repeat with the opposite end of the wire to your circuit.



At this stage you can choose to cut free the battery casing from the initial radio or use a separately sold casing, making sure that it does not exceed 70mm in width.
