The glass must not be touched within half an inch of the leads, and the leads are not to
be soldered nearer than half an inch from the glass to avoid contamination of the glass
Viewed from the base, with the red spot upwards, the connections are: top: anode; bottom: control grid;
left: filament -ve; right: filament +ve; centre: screen grid
