Introduzione
Nothing is more disappointing than building a radio just to find that it refuses to catch any signal in the FM world. I have come to find that this can occur in the Elenco model when the capacitor, C-22, is either broken or disconnected. This guide should be adequate in showing you how to remove and replace the capacitor.

-
-
Gently remove the capacitor by pulling the two leads out of the circuit board.
-
-
-
Place the leads of the capacitor through designated holes of the circuit board.
-
Place solder iron on the thermal pad and the lead.
-
Once this is done wait a few seconds until both items heat up.
-
Once they are heated, apply the solder to the other side so that the solder iron and the solder are not directly touching.
-
Wait 3 to 5 seconds or until enough solder covers the whole pad and forms a nice mound.
