Introduction

Radios are an everyday household item that are quite easy to break down after a few years or can wear down after many uses. Broken radios often just sit and collect dust and take up space. Fortunately, you can fix those radios and make them a functional device in your workspace. You’ll need some common hand tools and some replacement parts.

Once finished you can enjoy the sweet sounds of your favorite radio station.

Here some other guides to complete this project:

4 ohm 3W Speaker

Step 1

Observe what the problem is. Determine if the radio requires a Speaker change, an Antenna change or Both.
When the radio is on and all you hear is static and have cycled through some stations it is a good idea to assume the Antenna is broken
When the radio is on and you do not hear anything at all from the speaker with the volume up, then the Speaker is blown and needs replacing.

Step 2

After the diagnosis you can proceed to unscrew the Antenna located on the side of the plastic plate.
Using a #1 Phillips screwdriver, remove the 1 mm screw on the side of the radio.

Step 3

Remove the plastic holder for the Antenna to release its holding.
You will need to pull it out of its hole in order to do this. This can be done by hand, but if it is hard to remove use a pinching tool to remove it.

Step 4

Using a heat gun, loosen the glue holding the face of the radio.
Be careful not to overheat the radio.
Hold the heat gun about 3 inches from the radio face while moving away from it to prevent overheating.

Step 5

Use a plastic opening tool to remove the face of the radio.
Be sure to do this while the face is warm so the glue is still loose.
An easy way to remove the face is starting at a flat area and moving to the corners of the face while turning the tool to lift the face up.

Step 6

Remove the radio's Antenna and Battery.
Place the face of the radio to the side for access to the Speaker.
Gently pull back on the face of the radio.
The wires are short so be careful not to snap/tear them!

Step 7

Place the face of the radio to the side with the battery and thread the Antenna through the inside compartment to remove it.

Step 8

Pry out the Speaker from its holding position in the frame of the radio.
If the speaker is hard to remove use some heat to loosen the glue holding it.

Step 9

Unplug the Speaker Wire from the circuit by pinching the small clip and wiggling it out.
Do not pull the wire to remove the plug. This could break the wire.

Step 10

Cut the wires of the Speaker and the Antenna as close to the old parts as possible.
Cutting the wires close to the broken part ensures more working space and room for error

Step 11

Strip the ends of the wires where you cut so that some wire is exposed to solder to the new parts.

Step 12

Solder the positive and negative terminals of the Speaker with its respective wires.
Both positive and negative poles should be indicated on the speaker. If not, check out the link to find the polarity of your speaker.
Solder the new Antenna on.

Step 13

Place the Speaker back in the frame.
Fasten it down to make sure it holds. You can use glue around the edge to achieve this. Be sure it won't fall out when moved.
Place the Battery on top of the Speaker and plug in the Speaker Wire to the circuit of the radio.

Step 14

Take the Antenna and thread it through the hole at the top before placing it in the plastic holder at the bottom.
Replace the antenna screw to affix the antenna back onto the plastic base plate.

Step 15

Check that the Antenna can extend through the hole and place the plastic holder back in place.
Place the plastic ring back on to the Antenna opening.
