Vacuum Tube - 6E5, Indicator, ST Shape Glass
New-Old-Stock (NOS) tube.
The 6E5 is a high-vacuum, heater-cathode type of tube designed to indicate visually the effect of change in the controlling voltage. The tube, therefore, is essentially a voltage indicator and as such is particularly useful to facilitate exact tuning of a radio receiver. The visible effect is observed on a fluorescent target located in the dome of the bulb. For different controlling voltages, the pattern on the target varies through a shaded angle from 90 degrees to approximately 0 degrees. Exact tuning is indicated by the narrowest shaded angle obtainable.
Also known by US military identifier VT-215.
