This is the High Voltage Power Supply for the Tornado EHDD (Electronic Head Down Display).
The EHDD was fitted to the pilot’s cockpit of the Air Defence Variant of the Tornado. On the ADV the ground mapping radar display is not required, since all radar displays are basically synthetic. The pilot has the EHDD which is an extension of the Navigator’s TVTab display system. This gives the pilot full access to all data available to the Navigator and in addition provides head-down attack information and steering for interception.
The EHDD has three push-buttons and a rotary switch for mode selection and a rotary Brightness control. It uses a high brightness green monochrome Cathode Ray Tube made by Rank Brimar with a contrast enhancement filter, and a high voltage of 18kV was required for the final Anode of the CRT.
