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.

About RF Cafe

Webmaster:

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
