EIA Vacuum-Tube Base Diagrams

Base diagrams correspond to the codes in "Base" columns of the tube-data tables. Bottom views are shown throughout. Base connections are abbreviated as follows:

BS - Base Sleeve               NC - No Connection
F - Filament                        P - Plate
G - Grid PB                         F - Beam Plates
H- Heater                           S - Shell
IC - Internal Connection    K - Cathode
 
Alphabetical subscripts indicate structures in multistructure tubes.

D = diode, P = pentode, T = triode, HX = hexode
Subscript CT indicates filament or heater center tap.

Generally, when Pin 1 of a metal-envelope tube (except all triodes) is shown connected to the envelope, Pin 1 of a glass-envelope counterpart (suffix G or GT) is connected to an internal shield.
