The 4-400A and 4-400C are intended for use as amplifiers, oscillators or
 modulators.  The low grid-plate capacitance of these tetrodes couples 
with their low driving power requirement allow considerable 
simplification of the associated circuit and driver stage. 
They 
are cooled by radiation from the plate and by circulation of forced-air 
through the base, around the envelope, and over the plate seal.  Cooling
 can be greatly simplified by using the SK410 Air System socket and its 
accompanying glass chimney.
