It's 1993: Brian Hodgson and Delia Derbyshire discuss the creation of 'Doctor Who'. This is a rare and touching image of two of the great Radiophonic pioneers. At this time the original Studio A was equipped with a dubbing facilty, incorporating two Studer A80-VU twin-track tape machines with timecode centre tracks, a timecode reader with a large display and a timecode regenerator box.
