Convert a radio tape player to an MP3 Boombox

Step 2Desolder wires and unscrew cassette mechanism

Desolder wires and unscrew cassette mechanism
Here is the top side of the tape head where the wires *were* attached. I've already desoldered the four wires from it (positive and negative wires for the left and right channels).
To desolder the wires, just plug in the soldering iron and let it get fully heated up. Then just hold the tip of the iron to the solder pads while gently pulling on the wire. When the solder heats up enough to melt, the wire will come loose.
Follow the wires to where they attach to the electronics board in the player; it may be labeled there as to which is left and right.
I've also already desoldered the two wires from the tape player drive motor. We'll use those wires to power the MP3 player.
This picture also shows the headphones jack on the top of the player. We will "repurpose" that jack later on for use as the input.
You can also now remove any screws holding the cassette mechanism in so it can be removed.
