Toshiba RT-7760S vintage stereo boombox

A friend of mine asked me to repair this 1986 Toshiba stereo boombox for him.
There were a few failed solder joints on the selector switch, there was no sound from the right speaker and both belts of the cassette deck were broken.
I fixed the selector switch as well as the volume control that was the cause of the speaker not working and I also replaced the belts of the tape deck.
The only thing that doesn't work is AM radio which is complitely dead.
This is a very well made unit and also very high quality, it is simply a masterpiece, such a shame I have to give it back to my friend.
