Description
8 pieces of Telefunken EM800 magic bar tuning indicator tubes, NOS in sealed boxes Perfectly usable as bargraph display, for example for audio spectrum analyzers! Description EM800 :The EM800 is an indirectly heated (6,3 Volts, 0,3 Amp.) 9-pin luminescent vacuum bar indicator tube (magic bar), comparable with the tuning indicator tube EM84 = 6FG6 ~ 6E2 ~ EM87, but the EM800 shows only one luminescent green bar of variable length from 0 ... 30 mm along the main axis of its glass bulb. For more technical information please download the original Telefunken datasheet as pdf from *). More information is also provided at **). Because the EM800 indicator tube only shows one luminescent bar of controllable length, it is ideally applicable for establishing a bargraph display, implemented with a number of parallely mounted EM800. In the www an impressive example can be found, the EM800 Magilyzer, an audio spectrum analyzer with a bargraph display, consisting of six EM800. Condition:All eight tubes are boxed in original Telefunken boxes, that are still sealed. Thats why I cannot show the tubes directly. Please note: The EM800 tube I have used to demonstrate the display function on the photos belongs to my workshop equipment and is not offered here!
