1A quick test of this EM84 display tube which I found in my collection.
+250VDC on the anode, The grid is being operated between -20VDC and 0VDC. The heater on this tube is 6.3V.
Positive terminal on an isolated bench supply is connected to the ground of the +250V supply to give negative voltage required to drive the grid. The negative is fed into pin 1 via a 1meg resistor to ground.
