The EAM86 was designed as a level indicator for use in tape recorders. This is a small tuning indicator with a wide band of a screen for the display. The indication wraps round the circumference rather than along the length as is used in the EM84 and EM85.

Seen from the side the grids are clearly visible.

The thin glass tube envelope is 20 mm in diameter and, excluding the B9A base pins, is 40 mm tall.
