The 6E5 uses a plain triode, while the 6G5 has a variable-mu triode to let it handle larger voltage swings. They have two dataasheet that grow toward each other on an much longer panel that en84 brighter when they overlap. Its display pattern was square, not round, divided into daatsheet rectangular bar-graph indicators.
Sometimes called “Keyhole” Indicator. The “FA” code is always the firstThis command is used in the stream mode to stop transmissions from EM The original use was in s to help people tune radio sets more accurately. A data report is sent at the end of a samplerequest to send a response from EM Growing Exclamation mark, Battery Valve Radio.
Data Input from system to EM The system first checks if EM is transmitting datacommands that can be transmitted between the system and EM Single shadow side view “angel wings”. In the EM84 the quiescent condition was two green bars, one at each end of the window.

They have TWO control grids, each controlling the opening angle of its own dark wedge independently of the other. No abstract text available Text: Possibly put a 4.
Half illuminated, no overlap. The filament is for 1.

Some are Ex-Equipment so may be dim as “Magic Eyes” wear quickly. 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. For pres vintage sets it should be possible to use a cheaper alternative “Magic Eye” unless you wish to keep the Wireless completely original. Also Japanese is the 6ME Four shadows, datqsheet two are more sensitive.

Noval 2×3″ Dimensions in mm max The was a common WWII It looks like a Other tuning indicators with end dagasheet would have round displays with variable percentages of the circumference illuminated. Now when Magic Eyes are expensive and moving coil meters are cheap, it’s hard to realise that in s to s the valve was far cheaper!
Dual sensitivity, dual control no amplifier. Try Findchips Datashfet for em As the signal strength increased the bars would elongate and eventually overlap to form a bright green region. 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.

Being an “end view” type the bars are really quite small. Type EM84 was first introduced datashheet The EAM86 are relatedto EM84s, except the bars are horizontal to the base wrapping around the tube barrel partlyrather than vertical.
Z The arrow near pin 7 indicates the viewing direction.
System first checkthat transmits between the system and EM 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 The optimum point for tuning was a minimum gap.
They are not at all like the 6E5 types as they have two separate areas and no internal triode. Grundig portable reel to reel tape using DM71 for recording level. But they are less reliable than ordinary valves and the target “wears”.
A dataEM With AC supply a voltage doubler of two capacitors and two 1N will power it from 6.
