I have a very puzzling fault on this clock radio which is only evident on widely spaced stereo recordings, I seem to be only hearing one side of the recording (in mono) the other just comes through as a whisper. it suggests to me that the decoder fitted to this receiver is in fact a stereo one, which had not been connected up correctly for mono. It is very annoying on 60s recordings when the only thing I can hear is the backing track with the singer just an echo in the background
