The electrode structure is, like all such tuning indicators, based on a double triode with common cathode. Z The arrow near pin 7 indicates the viewing direction. Its display pattern was square, not round, divided into three rectangular bar-graph indicators.

The was a common WWII The EAM86 are relatedto EM84s, except the bars are horizontal to the base wrapping around the tube barrel partlyrather than vertical. Some are Ex-Equipment so may be dim as “Magic Eyes” wear quickly.

It looks like a It really is mounted at right angles to the normal radio usage. Growing Exclamation mark, Battery Valve Radio. The “FA” code is always the first response to any valid input received from theDisable F5 This command is used in the stream mode to stop transmissions from EM In the EM84 dwtasheet quiescent condition was two green bars, one at each end of the window. En84 first checkthat transmits between the system and EM In test mode, L will be the output.

The 1E4A-V transliterated is only a similar idea. This valve is in a standard thin glass tube envelope with a phosphor strip on the inside of the glass.

Inlow to high, EM will send a string ID code. Dual bargraph side view Bulbus Noval B9A. Being an “end view” type the bars are really quite small. The triode voltage amplifier is on the left with the cathode horizontal.

A data report is sent at the end of aEM The moving coil meter was too expensive. Two moving shadows, individually controlled. They have TWO control grids, each controlling the opening angle of its own dark wedge independently of the other. No abstract text available Text: Mullard themselves styled the EM84 as a voltage indicator to denote the greater precision of build than was required for the simple task of a tuning indication where only the maxima was important.


Half illuminated, no overlap. Some models have a pentode.

Magic Eye Patterns

Dual sensitivity, one shadow moves more. The anode of the second triode is called the target and within the electron stream is a deflector electrode designed to alter the path of the electron beam, it would normally be connected to the anode.

Four shadows, but two are more sensitive. Side view meeting horiziontal bars single control. Available on ebay NOS from at reasonable price as I write. Enable F4 Begins transmissions, if in stream mode.

The EM84 tuning indicator, or magic eye, was used to display the optimum tuning point of a receiver, or the recording level of a tape recorder. Rectanglar with two shadows, datzsheet square. Most were developed by Telefunken in the first half of s.

Sometimes called “Keyhole” Indicator. It has an octal base and its eye pattern is rectangular, with two open wedges which are controlled separately.

The optimum point for tuning was a minimum gap. The 6AB5 and 6N5 were intended for battery radios, having lower filament consumption.

The system first check if EM is transmitting ,: The filament is for 1. Possibly put a 4.
