The magic eye class of tuning indicator originated in the US and Type 6E5 was one of the earliest types. Almost all European types are more-or-less directly copied from it.
Early specimens, such as 6E5, had short lives due to 'burning' of the fluorescent target and poisoning of the cathode coating in the centre of the target area. This was later cured by enclosing the display part of the cathode within the spiral of a small space charge grid.
The display changes from open to closed for a 7.5 Volt change on the grid.
The end window envelope is 28 mm in diameter and, excluding the UX6 base pins, is 85 mm tall.
