Can you confirm there is no sound even in Gram and AM, and in FM that the magic eye is responding to tuning. If so, the EF89 is not your problem. The fault now lies with the audio section. I have a German user manual but that's not much use to me, and the switching is very complex.

1. Check the tape button is not depressed as it probably passes the audio through the tape input/output.

2. Check the speaker selection switch.

3. Switch to Gram and turn up the volume. Is there any hiss or hum? Do you get any clicking sounds when switching between gram and other sources?
