Hi, there is a pcb at right angles to the main board with several solder connections joining them. These joints can fail so it's worth while re-flowing them with a small amount of fresh solder. Also the bridge rectifier can give problems so replace this with four suitable diodes. I have two of these and even though the radios worked the sound improved greatly when the rectifier was changed.
