*: The EVS datasheet for this valve shows three possible constructions - the 'wafer base' as this example has, a tubular construction with a flat pinch with 5 leads inline, and a US type rectangular section bulb, again with 5 leads inline.
*: At Va=Vg2=30, Vg1=0.
The above table shows the leads for the wafer base type construction. Other construction styles have the 5 leads arranged as filament -ve + suppressor grid, control grid, filament +ve, screen grid, and anode, the anode lead being marked with a red dot.
