Notes:

Construction refers to both basing size and the envelope.

H/F means "Heater or Filament" voltage and current specifications.

(F) means "Filamentary", and (H-K) means "Heater-Cathode.

Numbers shown in light yellow background are used in series-string configurations.

Numbers shown in light blue background are cold-cathode tubes.

Numbers shown in light red are High-Voltage Rectifiers.

Numbers shown in light orange are power rectifiers.

Numbers shown in light green are for battery-operated radios.

Numbers may not show up where expected due to "combination" numbers -- e.g. 6CG7/6FQ7 -- if necessary use your browser's search feature (typically ctrl-F) to find them.
