The local oscillator looks slightly off tune. It is L5 [operation 7] on the Newnes circuit but better left alone if you don't feel confident about adjusting it. It's normally adjusted manually for maximum sound with freedom from sound on vision. If you are ok with this have a go, it will only require a tweak but take care so as not to damage the coil. Under no circumstances adjust any other tuning coil! John.
