6P14P-ER (original box)

Description

The output pentode 6P14P-ER is used in the output single-cycle and push-pull circuits of low-frequency receivers and amplifiers. Designed to amplify low-frequency power in general-purpose radio-electronic equipment.

E – characterizes the increased durability of the tube;
R – characterizes the increased reliability of the tube.
