Stereo KENWOOD

Manufacturer: KENWOOD
Type: KR-A3080

Description of failure

The stored radio stations are lost after switching off and on.

Failure investigation

The radio contains a supercap, which is responsible for the station memory. This is a 5.5V 47mF type, which is defective. A 47mF replacement type could not be found in the right size, but a larger one with 100mF (Korchip DCS5R5104HF). A supercap with more capacity is not a problem here. After replacing the component, the radio stations are still present after switching off and on.
