The following codes are recommended as standards to be employedwith traveling wave tubes, klystron tubes or crossed field devices.that are equipped with flying leads. It is intended that theinsulation of the leads be colored and that these leads be anintegral part of the tubes as supplied by the manufacturer.Spaghetti or other nonpermanent means of identifying lead colorsshould not be used.
Inasmuch as a color code is valuable only if the colors areeasily identifiable, it is suggested that EIA Standard GEN-101-AColor Coding for Numerical Values be employed with the color limitsas established by Supplement 1 to EIA GEN-101-A, Standard ColorChips.
Since different grids and possible combination of grids may beemployed to control current no attempt is made to separate the”anode” or “control grid” from the others. The grids and helicesare numbered 1, 2, 3, . . . ,, according to their relative positionfrom the cathode, the lowest number being closest to the cathode.Numbers for grids or helices not available externally are omitted.Where two helices are equidistant from the cathode, the lowervoltage helix will be assigned the lower number.
