New project and new problem.
I restore a SHARP GF-555 but neither with the cassette and nor with the radio I have sound, just a low background noise.
On the other hand when I use the rca line, the sound is present and powerful.
I visually controlled the capacitors of the card and the fuse, everything is good.

Any idea?

Thank you
